Title: Brazing material, brazing member, heat exchanger, and producing method of brazing member

Description:
TECHNICAL FIELD 
     The present invention relates to a brazing material, a brazing member, a heat exchanger, and a method for producing a brazing member, to be specific, to a brazing material for brazing aluminum or an aluminum alloy, a brazing member including a coating film formed by applying the brazing material, a heat exchanger including the brazing member, and furthermore, a method for producing a brazing member for producing the brazing member. 
     BACKGROUND ART 
     Conventionally, flux is used to remove oxides of metal members that are welded when the metal members are welded. 
     Since the flux is usually liquid, the flux may flow when applied to a welding site. When the flux is liquid, a dry facility for a solvent is required to solidify a coating film, which may cause complication of the production line, and furthermore, the workability may be inferior due to scattering of the liquid flux and the like. 
     Therefore, in order to achieve simplification of the production line and improve the workability, it has been considered to use solid flux, and a brazing composition formed by uniformly blending a brazing material powder, a fluoride-based flux powder, and a solid wax at normal temperature has been, for example, proposed. It has also been proposed to form a coating layer for brazing by melting the blazing composition and applying it to the surface of an aluminum material (ref: for example, Patent Document 1 below). 
     For example, it has been proposed that, after mixing a metal powder for brazing, a paraffin wax, and flux for brazing, the resulting mixture is water-dispersed to be used as a composition for brazing (ref: for example, Patent Document 2 below).

     SUMMARY OF THE INVENTION 
     Problem to be Solved by the Invention 
     On the other hand, when the above-described solid brazing composition at normal temperature is melted and liquefied to be applied to an object to be coated, there is a problem that the dispersibility of a fluoride-based flux powder is not sufficient and the brazing properties are inferior. In addition, there is a problem that the application properties (liquid application properties) are not sufficient when the brazing composition is liquefied to be applied to the objected to be coated. 
     Further, it is also considered that the brazing composition is applied to an object to be coated by bringing the above-described solid brazing composition at normal temperature into contact with the object to be coated in a solid state and rubbing it if necessary. In this case, from the viewpoint of application properties, it is required to form the brazing composition into a desired shape. However, since the above-described brazing composition does not have sufficient moldability, it is difficult to form it into a desired shape, and as a result, it is inferior in application properties in a solid state (solid application properties). 
     The present invention provides a brazing material which has excellent brazing properties and excellent application properties (liquid application properties and solid application properties), while achieving simplification of the production line and improving workability, a brazing member including a coating film formed by applying the brazing material, a heat exchanger including the brazing member, and furthermore, a method for producing a brazing member.

     More specifically, examples of the brazing filler metal include a metal silicon, a silicon-aluminum alloy, and these alloys containing a small amount of magnesium, copper, and germanium. 
     Further, the brazing filler metal is preferably prepared in a powder form. That is, as the brazing filler metal, preferably, a brazing filler metal powder is used. An average particle size of the brazing metal filler powder is not particularly limited, and is appropriately set in accordance with the purpose and the application. 
     When the brazing material includes the brazing filler metal, it has excellent work efficiency in the brazing of the aluminum and the aluminum alloy.

     The brazing material may contain a gelling agent, if necessary, and preferably does not contain a gelling agent from the viewpoint of brazing properties (appearance). 
     Then, the brazing material can be obtained by mixing and stirring each of the above-described components at the above-described mixing ratio by a known method. At this time, the fluoride-based flux is dispersed by the organic viscosity reducing agent, and the brazing material is solidified by the solidifying agent. 
     That is, the above-described brazing material is solid, and specifically, is solid at 25° C. 
     Solid at 25° C. is defined as “not in liquid form” as a result of the test conducted at 25° C. in accordance with the method described in the “Method of Confirmation of Liquid Status” described in the “Notice No. 11 of the Office of Hazardous Materials Regulation-Cabinet Order for Partial Revision of the Cabinet Order Concerning the Control of Hazardous Materials (Part Relating to Examination and Property of Hazardous Materials) and the Promulgation of the Ministerial Order on Examination and Property of Hazardous Materials (Notification)”. 
     The brazing material is softened by heating. 
     More specifically, when, for example, the above-described brazing material is applied to the aluminum or the aluminum alloy, as the details are described later, the solid brazing material is softened and melted by heating. 
     A heating temperature is, for example, 40° C. or more, preferably 60° C. or more, more preferably 70° C. or more, further more preferably 80° C. or more, particularly preferably 90° C. or more, and for example, 400° C. or less, preferably 300° C. or less, more preferably 200° C. or less, further more preferably 180° C. or less, particularly preferably 150° C. or less. 
     That is, particularly preferably, the above-described brazing material is melted at 150° C. or less. In other words, the brazing material is preferably in a melting state at least at 150° C. 
     In such a case, the viscosity at 150° C. (melting state) of the brazing material is, for example, 0.001 Pa·s or more, preferably 0.003 Pa·s or more, more preferably 0.006 Pa·s or more, further more preferably 0.02 Pa·s or more, particularly preferably 0.05 Pa·s or more, and for example, 300 Pa·s or less, preferably 100 Pa·s or less, more preferably 10 Pa·s or less, further more preferably 5 Pa·s or less, further more preferably 1 Pa·s or less, particularly preferably 0.1 Pa·s or less. 
     When the viscosity at 150° C. is within the above-described range, it is possible to obtain particularly excellent application properties. 
     The viscosity at 150° C. is measured with a rheometer in conformity with Examples to be described later. 
     A melted material of the brazing material is then applied to the aluminum or the aluminum alloy to subsequently form a coating film by solidification (solid coating film). 
     An application method is not particularly limited, and examples thereof include a brush coating method, a roll coating method, a spin coating method, a dip coating method, a spray coating method, a bar coating method, a knife coating method, a dye coating method, an inkjet method, a jet dispensing method, and a gravure coating method. From the viewpoint of application properties and coating film solidification properties, preferably, a jet dispensing method is used. 
     By applying the brazing material by the jet dispensing method, it is possible to more accurately apply the brazing material to a desired position, and also, it is possible to quickly solidify the brazing material to obtain a desired solidified coating film. 
     A thickness of the solidified coating film may be appropriately set in accordance with the purpose and the application. 
     Then, since such a brazing material is solid at 25° C., it is possible to improve the workability in brazing of the aluminum or the aluminum alloy. 
     That is, for example, the application of the liquid or paste-like brazing material to a metal member may contaminate the application facility and the surroundings thereof with the low melting point organic compound, and there is a problem of taking the labor and time in the maintenance of the facility. 
     On the other hand, when the solid brazing material is heated at 25° C., melted, and applied, the scattering of the brazing material droplets can be reduced, so that the contamination of the application facility and the surroundings thereof can be suppressed. 
     In addition, since the above-described brazing material is solid at 25° C., the solidification is faster than that of the liquid brazing material even after heating and melting, so that it is possible to achieve the simplification of the production line and improve the workability. 
     Furthermore, since the above-described brazing material includes the fluoride-based flux, the solidifying agent, and the organic viscosity reducing agent, it is possible to achieve the low viscosity at the time of melting, and it also has excellent brazing properties and excellent application properties (liquid application properties). 
     In addition, the above-described brazing material also has excellent application properties when applied in contact with an object to be coated in a solid state. 
     Therefore, the above-described brazing material is preferably used for the aluminum or an aluminum alloy product. Specifically, the above-described brazing material is preferably used in the production of a brazing member including the aluminum or the aluminum alloy, or in the production of a heat exchanger using the brazing member. 
     In the following, the brazing member and the heat exchanger are described in detail. 
     In  FIG. 1 , a heat exchanger  1  is, for example, a laminated heat exchanger used in an air conditioner or the like, and has a known laminated structure. 
     Specifically, the heat exchanger  1  includes a tube laminate  3  formed by laminating a plurality of plate connecting tubes  2  and a refrigerant supply and discharge pipe  4  for supplying and discharging a refrigerant to the tube laminate  3 . 
     In the tube laminate  3 , the plate connecting tube  2  is a hollow member having a generally flat shape, and as shown in  FIG. 2 , includes a pair of (two) plate members  5  disposed opposite to each other and two inner fins  6  disposed at the inside of the plate members  5 . 
     Each of the plate members  5  is a member (Al member) made of the aluminum or the aluminum alloy, has a generally long rectangular shape when viewed from the top, and has a generally rectangular recessed portion  7  when viewed from the top extending along a longitudinal direction in a generally central portion in the longitudinal direction thereof (region excluding both end portions in the longitudinal direction). 
     In the recessed portion  7 , a protruding portion  8  (rib) extending along the longitudinal direction of the recessed portion  7  is erected in the central portion in a width direction perpendicular to the longitudinal direction. That is, the recessed portion  7  is divided into a recessed portion  7   a  at one side in the width direction and a recessed portion  7   b  at the other side in the width direction by the protruding portion  8 . 
     Further, a first through hole  9  is formed in one-side end portion in the longitudinal direction of the recessed portion  7   a.    
     Further, a second through hole  10  is formed in the other-side end portion in the longitudinal direction of the recessed portion  7   a.    
     Further, a third through hole  11  is formed in one-side end portion in the longitudinal direction of the recessed portion  7   b.    
     Further, a fourth through hole  12  is formed in the other-side end portion in the longitudinal direction of the recessed portion  7   b.    
     A groove  13  is formed between the first through hole  9  and the third through hole  11 , and thus, a refrigerant (described later) is allowed to flow between the first through hole  9  and the third through hole  11 . The groove  13  is not formed between the second through hole  10  and the fourth through hole  12 , and they are independent of each other. 
     The inner fin  6  is a member (Al member) made of the aluminum or the aluminum alloy, and one inner fin  6  is provided in the recessed portion  7   a  and one inner fin  6  is provided in the recessed portion  7   b  (two in total). Specifically, each of the inner fins  6  has a corrugated plate shape having generally the same size as the recessed portion  7   a  and the recessed portion  7   b , and can be accommodated in a refrigerant passage  15  (described later). 
     Then, as the details are described later, the plate connecting tube  2  is formed by brazing the pair of plate members  5  and the inner fin  6  described above. 
     As shown in  FIG. 1 , the plurality of obtained plate connecting tubes  2  are laminated so that the first through hole  9 , the second through hole  10 , the third through hole  11 , and the fourth through hole  12  are overlapped with each other to form a refrigerant supply and discharge passage  16 . Then, the laminated plate connecting tubes  2  are fixed by outer plates  17  from both sides in a laminating direction. 
     More specifically, the first through hole  9 , the second through hole  10 , the third through hole  11 , and the fourth through hole  12  are sealed by the outer plate  17  at one side (rear side) in the laminating direction. On the other hand, the third through hole  11  and the fourth through hole  12  are sealed by the outer plate  17  at the other side (front side) in the laminating direction, and the first through hole  9  and the second through hole  10  are opened. 
     Thus, the tube laminate  3  is obtained. In the tube laminate  3 , if necessary, a partition plate for adjusting the flow path of the refrigerant and an outer fin for improving the heat exchange efficiency may be provided between the plate connecting tubes  2 . 
     The refrigerant supply and discharge pipe  4  includes a refrigerant supply pipe  18  for supplying a refrigerant to the tube laminate  3 , and a refrigerant discharge pipe  19  for discharging the refrigerant from the tube laminate  3 . 
     One-side end portion of the refrigerant supply pipe  18  is connected to the first through hole  9 , and the other-side end portion thereof is connected to a refrigerant tank which is not shown. In the refrigerant tank, for example, a known refrigerant such as hydrofluoroolefin is stored. 
     One-side end portion of the refrigerant discharge pipe  19  is connected to the second through hole  10 , and the other-side end portion thereof is connected to a refrigerant collection tank which is not shown. 
     Then, in the heat exchanger  1 , by supplying a refrigerant X from the refrigerant supply pipe  18  to the refrigerant passage  15  at the inside of the plate connecting tube  2 , heat exchange of the refrigerant X flowing at the inside of the tube laminate  3  with air Y for air conditioning flowing at the outside of the tube laminate  3  is carried out, and it is possible to cool the air Y for air conditioning. 
     In the following, a method for producing the plate connecting tube  2  and a brazing plate  20  as a brazing member for obtaining the plate connecting tube  2  is described in detail. 
     That is, in the production of the plate connecting tube  2 , first, the brazing plate  20  including the plate member  5  (Al member) and a coating film  29  of the brazing material formed on the surface of the plate member  5  is produced, and then, the obtained brazing plate  20  and the above-described inner fin  6  are brazed. 
     In the production of the brazing plate  20 , for example, as shown in  FIG. 3 , a substrate  22  (hereinafter, referred to as an Al substrate) made of the aluminum or the aluminum alloy on a thin plate is prepared to process the Al substrate  22 , and then, the above-described brazing material is applied to the Al substrate  22 . 
     In  FIG. 3 , the Al substrate  22  is, for example, moved in a predetermined direction by a moving device  23  such as a belt conveyor (for example, from the left to the right on the plane of the sheet). 
     Then,  FIG. 3A  (processing step) and  FIG. 3B  (application step) shown below are continuously carried out from the upstream side toward the downstream side of the moving device  23  in order. 
     That is, in this method, as referred to  FIG. 3A , first, the Al substrate  22  is processed (processing step). 
     More specifically, in the production line, while the Al substrate  22  is intermittently moved in a predetermined direction, the Al substrate  22  is processed and formed into a predetermined shape (for example, shape of the plate member  5  described above). 
     The processing method is not particularly limited, and for, example, a known processing device  30  such as a press processing device, a bending processing device, and a cutting processing device is used. 
     Thus, the plate member  5  (ref:  FIG. 2 ) is obtained as the Al substrate  22  after processing. 
     Then, in this method, as shown in  FIG. 3B , a brazing material  27  described above is heated and melted, and a resulting liquid melting composition  28  is applied to the plate member  5  (application step). 
     More specifically, in the application step, the melting composition  28  of the brazing material  27  is applied to the recessed portion  7  of the plate member  5  (ref:  FIG. 2 ). 
     For example, as described above, a heating temperature of the brazing material  27  is, for example, 40° C. or more, preferably 60° C. or more, more preferably 70° C. or more, further more preferably 80° C. or more, particularly preferably 90° C. or more, and for example, 400° C. or less, preferably 300° C. or less, more preferably 200° C. or less, further more preferably 180° C. or less, particularly preferably 150° C. or less. 
     Further, a method of applying the melting composition  28  is not particularly limited, and a jet dispensing method is preferably used when the application region is narrow and the precise application is required. That is, preferably, the melting composition  28  is supplied to a discharge device  31  such as a jet dispenser, and is discharged toward the plate member  5  (the Al substrate  22 ). 
     The discharge conditions (temperature, pressure, and the like) in the discharge device  31  (jet dispenser and the like) are appropriately set in accordance with the purpose and the application. 
     By using the discharge device  31  (jet dispenser and the like), the melting composition  28  can be more accurately applied to a desired position, and can be solidified quickly to obtain the desired coating film (solidified coating film)  29 . 
     That is, since the solidification of the above-described brazing material  27  is faster than that of the liquid brazing material when heated and melted, the above-described brazing material  27  is spontaneously solidified without a drying step, and the coating film  29  can be formed. Therefore, the above-described brazing material  27  has excellent industrial productivity of the coating film  29 . 
     A thickness of the coating film  29  is not particularly limited, and is, for example, 1 μm or more, preferably 5 μm or more, and for example, 1000 μm or less, preferably 200 μm or less. 
     Thus, the brazing plate  20  including the plate member  5  (the Al substrate  22 ) and the coating film  29  can be obtained. 
     Then, since the brazing plate  20  includes the coating film  29  formed by applying the above-described brazing material  27  to the plate member  5  (the AL substrate  22 ), it can have excellent brazing properties. 
     Therefore, the resulting brazing plate  20  is preferably used in the production of the plate connecting tube  2  and the heat exchanger  1 . 
     More specifically, as referred to  FIGS. 1 and 2 , the pair of brazing plates  20  (the plate members  5 ) are oppositely disposed, and the inner fins  6  are disposed between the pair of brazing plates  20  (the plate members  5 ) so as to correspond to the recessed portion  7   a  and the recessed portion  7   b.    
     Then, each of the inner fins  6 , the recessed portion  7   a , and the recessed portion  7   b  are brazed, and along with this, the contact portions (peripheral end edges and the protruding portions  8 ) of the pair of brazing plates  20  (the plate members  5 ) are brazed to each other. 
     Thus, the pair of brazing plates  20  (the plate members  5 ) are connected, and the recessed portion  7   a  and the recessed portion  7   b  facing each other form a hollow space to form the two refrigerant passages  15 . Further, the inner fin  6  is fixed to the refrigerant passage  15 . 
     In this way, it is possible to obtain the plate connecting tube  2 , and by laminating the plate connecting tube  2 , it is also possible to obtain the heat exchanger  1 . 
     Since the obtained heat exchanger  1  is obtained using the brazing plate  20  described above, it can have excellent brazing properties. 
     In addition, in the method for producing the brazing plate  20  described above, since the above-described brazing material  27  is used, the solidification of the coating film  29  is fast. Therefore, according to the method for producing the brazing plate  20  described above, the processing step of processing the Al substrate  22  (aluminum or aluminum alloy) and the application step of discharging the brazing material  27  can be carried out in the same production line, and it is possible to achieve the simplification of the production line and improve the workability. 
     Therefore, the brazing member and the heat exchanger described above can be, for example, preferably used as a heat exchanger for an air conditioner used in a cabin of an automobile and a room of a house. 
     In the above-described description, the melting composition  28  obtained by heating the solid brazing material  27  is applied to the plate member  5 . Alternatively, the solid brazing material  27  can be also applied by being brought into contact with the plate member  5  without melting in a solid state and by rubbing if necessary. 
     In such a case, an example of the application method includes a method in which as described in International Publication WO2018/235906, the plate member  5  is wound with a roll-type conveyance device or the like in a state where the long plate member  5  and the brazing material  27  are in contact with each other, and the plate member  5  is relatively moved with respect to the brazing material  27 . By the method, the solid brazing material  27  is shaved, and the shaved brazing material  27  is attached (applied) to the plate member  5 . 
     Then, by using the above-described brazing material  27 , it also has excellent application properties when applied in contact with an object to be coated in a solid state. 
     EXAMPLES 
     Next, the present invention is described based on Examples and Comparative Examples. The present invention is however not limited by the following Examples. All designations of “part” or “parts” and “%” mean part or parts by mass and % by mass, respectively, unless otherwise particularly specified in the following description. The specific numerical values in mixing ratio (content ratio), property value, and parameter used in the following description can be replaced with upper limit values (numerical values defined as “or less” or “below”) or lower limit values (numerical values defined as “or more” or “above”) of corresponding numerical values in mixing ratio (content ratio), property value, and parameter described in the above-described “DESCRIPTION OF EMBODIMENTS”. 
     1. Production of Brazing Material 
     Example 1 
     A brazing material was obtained in accordance with the mixing formulation shown in Table 1. 
     Specifically, 33.3 parts of aluminate fluoride potassium flux, 64.7 parts of a paraffin wax, and 2.0 parts of a surfactant (polyoxyethylene lauryl ether, HLB: 16.9) were heated and mixed, poured into a predetermined mold, and cooled and molded, thereby obtaining a brazing material. 
     The brazing material was solid at 25° C. 
     Examples 2 to 69 and Comparative Examples 1 to 2 
     A brazing material was obtained in the same manner as in Example 1, except that the mixing formulation was changed to that shown in Tables 1 to 8. 
     As a brazing filler metal, Al-12% Si is an Al brazing filler metal containing 12% of Si (trade name: ECKA Aluminium-Silicon 12AN&lt;0.025 mm, manufactured by ECKA Granules Germany GmbH). 
     Further, as the brazing filler metal, Si is a Si brazing filler metal (trade name: M-Si SH-2 fine powder, product of 45 μm, manufactured by KINSEI MATEC CO., LTD.). 
     2. Viscosity at Melting at 150° C. 
     Each of the brazing materials of Examples and Comparative Examples was heated at 150° C. and melted, and then, the viscosity at a shear rate of 2/s was measured using a rheometer (manufactured by Anton Paar GmbH, Physica MCR 301, jig: PP25, measurement position: 0.5 mm), while kept at 150° C. 
     When the brazing material contained a component boiled at 150° C. or less (referred to as a low boiling point component) such as water and a low melting point organic compound, the viscosity was measured at temperature of three points (for example, 60° C., 75° C., and 90° C. in Examples 19 and 20) which was the temperature at which an organic component of the brazing material melted or more and the boiling point of the low boiling point component or less, and the viscosity at 150° C. was calculated by linear extrapolation. 
     The viscosity at the melting at 150° C. is shown in Tables 1 to 8. 
     3. Evaluation 
     (1) Application Properties 
     (1-1) Liquid Application Properties 
     After each of the brazing materials of Examples and Comparative Examples was heated at 95° C. and melted, it was supplied to a discharge device (non-contact-type jet dispenser, manufactured by Musashi Engineering, Inc., hot melt-compatible AeroJet (syringe: PSY-30FH-P, rod: M35-2582-079-00, valve sheet: V, nozzle caliber: 0.29 mm)), and one shot was discharged to an aluminum member (150 mm×70 mm×0.8 mm) under the conditions of spring: 100%, nozzle temperature control: 95° C., syringe temperature control: 120° C., syringe pressure: 30 kPa, stroke: 0.3 mm, on time: 2 msec, and clearance: 1 mm to fabricate a test piece. Then, an amount of application of the fluoride-based flux in the applied range was evaluated as superior or inferior based on the following criteria. The results are shown in Tables 1 to 8. 
     In addition, a case where the brazing material can be stably applied and a thinner coating film can be formed was defined as a case with excellent application properties. 
     S: The application was carried out at 5 g/m 2  or more and below 20 g/m 2 . 
     A: The application was carried out at 20 g/m 2  or more and below 50 g/m 2 . 
     B: The application was carried out at 50 g/m 2  or more and below 150 g/m 2 . 
     C: The application was carried out at 150 g/m 2  or more and below 300 g/m 2 . 
     D: The application was carried out at 300 g/m 2  or more. 
     E: The application was carried out at 300 g/m 2  or more without stability. 
     Bad: Discharge was not carried out due to clogging in the discharge device. 
     (1-2) Solid Application Properties 
     Each of the brazing materials of Examples and Comparative Examples was melted at 100° C., fed into a cylindrical mold (10-cm aluminum siphon cake mold) with a diameter of 10 cm (inner diameter of 9 cm), and left to stand at room temperature for one hour to be solidified. A rotational axis was inserted into the inner space of the obtained cylindrical sample, and the sample was shaved so that a width of the curved surface was 5 cm and the curved surface was parallel to the rotational axis to produce a sample for application. 
     Subsequently, the obtained cylindrical sample was set in a solid material pressing machine (manufactured by DAISEKI Co., Ltd.) and pressed against an aluminum substrate (length: 250 m, width: 5 cm, thickness: 100 μm) conveyed at 150 m/min. At this time, the rotational axis of the sample was rotated at 2000 rpm with a drill (manufactured by Makita Corporation, DF-458D), with a set load of 10 kg. 
     Thus, the aluminum substrate in which the brazing material was applied in a solid state was obtained. Thereafter, an amount of application of the fluoride-based flux in the applied range was evaluated as superior or inferior based on the following criteria. The results are shown in Tables 1 to 8. 
     In addition, a case where the brazing material can be stably applied and a thinner coating film can be formed was defined as a case with excellent application properties. 
     S: The application was carried out at 0.5 g/m 2  or more and below 10 g/m 2 . 
     A: The application was carried out at 10 g/m 2  or more and below 20 g/m 2 . 
     B: The application was carried out at 20 g/m 2  or more and below 50 g/m 2 . 
     C: The application was carried out at 50 g/m 2  or more and below 150 g/m 2 . 
     D: The application was carried out at 150 g/m 2  or more and below 300 g/m 2  without stability. 
     Bad: The application was not carried out due to extremely soft sample. 
     *: The brazing material was melted at 100° C. and fed into a cylindrical mold. However, it was not possible to evaluate the application properties because the melted brazing material was not a homogeneous-shaped liquid, and the required cylindrical and solid brazing material could not be obtained. The phenomenon of not becoming a liquid having a homogeneous shape was the same even when heated to a further higher temperature than 100° C. 
     (2) Coating Film Solidification Properties After each of the brazing materials of Examples and Comparative Examples was heated at 95° C. and melted, it was supplied to a discharge device (non-contact-type jet dispenser, manufactured by Musashi Engineering, Inc., hot melt-compatible AeroJet (syringe: PSY-30FH-P, rod: M35-2582-079-00, valve sheet: V, nozzle caliber: 0.29 mm)), and one shot was discharged to an aluminum member (150 mm×70 mm×0.8 mm) under the conditions of spring: 100%, nozzle temperature control: 95° C., syringe temperature control: 95° C., syringe pressure: 30 kPa, stroke: 0.3 mm, on time: 2 msec, and clearance: 1 mm to fabricate a test piece. Then, the superiority and the inferiority were evaluated based on the following criteria. The results are shown in Tables 1 to 8. 
     A: Immediately after the application, a solid coating film was formed. 
     B: After the application, a liquid coating film was formed, and when it was left to stand at 25° C. for 30 seconds, it became a solid coating film. 
     C: After the application, a liquid coating film was formed, and when it was left to stand at 25° C. for one minute, it became a solid coating film. 
     Bad: After the application, a liquid coating film was formed, and even when it was left to stand at 25° C. for one minute, it remained in a liquid coating film. 
     (3) Brazing Properties 
     (3-1) Appearance 
     Each of the brazing materials of Examples and Comparative Examples was heated at 90° C. and melted, and then, applied to an aluminum member (150 mm×70 mm×0.8 mm) with a 10-mm diameter circle so that an amount of application of the fluoride-based flux was 10 g/m 2 , and a test piece was produced. 
     Thereafter, the above-described test piece was heated at 600° C. and brazed using a brazing furnace (box-type electric oven, manufactured by NORITAKE TCF, Co., Limited, A (V)-DC-M) under a nitrogen gas atmosphere (oxygen concentration of 100 ppm or less). 
     Then, the superiority and the inferiority of the performance were evaluated in the following test. The results are shown in Tables 1 to 8. 
     The appearance after the brazing test was visually evaluated based on the following criteria. 
     A: Black was hardly seen. 
     B: Black was seen in a part of the application region. 
     Bad: Strong black was clearly seen throughout the application region. 
     (3-2) Shortage of Brazing 
     After each of the brazing materials of Examples and Comparative Examples was heated at 90° C. and melted, it was applied to the entire surface of an aluminum member (JIS-BAS121P (cladding rate of 10%), 60 mm×25 mm×1.0 mm) made of a brazing sheet clad with a silicon-aluminum alloy (brazing filler metal) on an aluminum alloy by brushing so that an amount of application of the fluoride-based flux was 10 g/m 2  to be produced as a horizontal material. Next, an aluminum alloy (JIS-A3003, 55 mm×25 mm×1.0 mm) as a vertical material was installed to the horizontal material in an inverted T-shape and fixed with a stainless steel wire to produce a test piece for brazing evaluation. 
     Thereafter, the above-described test piece was heated at 600° C. and brazed using a brazing furnace (box-type electric oven, manufactured by NORITAKE TCF, Co., Limited, A (V)-DC-M) under a nitrogen gas atmosphere (oxygen concentration of 100 ppm or less). 
     Then, the superiority and the inferiority of the performance were evaluated in the following test. The results are shown in Tables 1 to 8. 
     A fillet after the brazing test was visually evaluated based on the following criteria: 
     Excellent: A fillet was formed uninterruptedly throughout the area where the horizontal material and the vertical material were in contact. 
     Bad: Although a fillet was formed in a part of the area where the horizontal material and the vertical material are in contact, the dispersibility of the fluoride-based flux was poor and the application was not uniformly carried out, so that discontinuation was confirmed in the fillet.
