Talk:Brass

message: This article seems to imply that, while some brasses are called "bronze", this is incorrect:
Some types of brass are called bronzes, despite their high zinc content.
On the other hand, the bronze article indicates that "bronze" is a general term for copper alloys, and therefore includes brass:
brass, a subset of the bronze alloys in which zinc is the principal additive
I am not qualified to judge which of these is correct, but they seem to contradict each other.

text: Lead has been a common additive in many different types of brass. The small nodules of lead act as a lubricant and make the brass easier to cut and machine. For example, a very common type of brass is C360000(Often designated as simply C360). It is also referred to as "free machining brass", as it is the alloy of brass with the highest "machinability" rating. In fact, it is considered to be the reference alloy for machinability. C360 brass contains 3% lead. Brass used in pipe fittings for potable water systems contained lead until very recently when it began to be removed to meet RoHS standards.Gcronau (talk) 10:13, 19 August 2015 (UTC)
thread_title:  Brass vs. Bronze 

message: Dear editor,
Is there an appreciable difference in cost for Brass as compared to Bronze? What would be the basic difference? Is there a "rule of thumb" when it comes to pricing one verse the other e.g. a standard ratio?
Thanks

thread_title:  Saltwater effects on Brass 

message: On UK radio (Radio 2) today (14th March 2007) they have just announced that one hospital is testing the effectiveness of using a small piece of copper on door handles to act as a disinfectant that kills the super bug MRSA amongst others. Does anyone know if the copper content in brass is equally effective at killing germs and viruses? If so replacing all door handles with brass would seem an obvious solution to the spread of germs from touching door handles!

message: There is evidently no extant WikiProject which deals with articles concerning alloys and other chemical compounds. This could be a problem, as many of these articles deal with what are considered to be generally important topics. To correct this situation, I have proposed a project to deal with these articles at Wikipedia:WikiProject Council/Proposals#Chemical compounds and mixtures. Anyone interested in contributing to such a project should indicate as much there. Thank you for your attention. John Carter 20:34, 28 April 2007 (UTC)

thread_title:  Akkadian brass 

message: Admiralty brass contains 30% zinc and 1% tin which inhibits dezincification in most environments. 
Alpha brasses (Prince's metal), with less than 35% zinc, are malleable, can be worked cold, and are used in pressing, forging, or similar applications. They contain only one phase, with face-centered cubic crystal structure. 
Alpha-beta brass (Muntz metal), also called duplex brass, is 35-45% zinc and is suited for hot working. It contains both α and β' phase; the β'-phase is body-centered cubic and is harder and stronger than α. Alpha-beta brasses are usually worked hot. 
Aluminium brass contains aluminium, which improves its corrosion resistance. Used in Euro coins (Nordic gold). 
Arsenical brass contains an addition of arsenic and frequently aluminium and is used for boiler fireboxes. 
Beta brasses, with 45-50% zinc content, can only be worked hot, and are harder, stronger, and suitable for casting. 
Cartridge brass is a 30% zinc brass with good cold working properties. 
Common brass, or rivet brass, is a 37% zinc brass, cheap and standard for cold working. 
DZR brass is Dezincification resistant Brass with a small percentage of Arsenic. 
Gilding metal is the softest type of brass commonly available. An alloy of 95% copper and 5% zinc, gilding metal is typically used for ammunition components. 
High brass, contains 65% copper and 35% zinc, has a high tensile strength and is used for springs, screws, rivets. 
Leaded brass is an alpha-beta brass with an addition of lead. It has excellent machinability. 
Low brass is a copper-zinc alloy containing 20% zinc with a light golden color, excellent ductility and is used for flexible metal hoses and metal bellows. 
Naval brass, similar to admiralty brass, is a 40% zinc brass and 1% tin. 
Red brass, while not technically brass, is an American term for CuZnSn alloy known as gunmetal. 
Rich low brass contains 85% copper 15% zinc often used in jewelry applications . 
White brass contains more than 50% zinc and is too brittle for general use. 
Yellow brass is an American term for 33% zinc brass.  —Preceding unsigned comment added by 219.64.95.125 (talk) 17:16, 13 August 2008 (UTC)

thread_title:  History of Brass - Africa, Americas and East Asia 

message: The previous section (SDC10257.JPG) explains a lot, but the rules of kindness suggest responding when asked. So, here we go: Cast alloys usu. have a dendritic type microstructure, or at least somewhat directional shape of grains (single crystals). In sdc10257.jpg, there are no dendrites, and the grains show no special orientation (meaning elongation). If one looks at sdc10257.jpg, sees rather unoriented grain shape, with random orientation of crystallographic axes (brightness of each grain), there are twins typical of deformed and annealed alloys with fcc structure (annealing twins, produced by recrystallisation).
In March 2009, I made the comment to the description of the image (see File_talk:SDC10257.JPG), but there was no further discussion. Apparently, it's easier to discuss on the referring page than on the original file's talk page. It's also easy to undo a change without deep investigation into the issue.

thread_title:  Bass alloys table 

message: The opening paragraph of the properties section (as of 5 Jan 2014) implies that the Brass Section of an orchestra contains instruments made out of brass.  It continues by noting that other instruments belong to other orchestral sections despite being made out of brass.  The implication is that an instrument made out of brass belongs in the brass section.  This is misleading and incorrect.
In truth, the orchestral brass section is so named because, historically, those instruments were made from brass.  Those instruments also use pursed lips on the mouthpiece to create the sound.  The brass section could easily have been named the embouchure section, but it didn't happen that way.
Instruments in other orchestral sections may also use brass, but that is done for its tonal qualities.  There is no reason that other instruments using brass (woodwinds, percussion, or otherwise) should be called brass instruments and no justification is needed for their exclusion from the orchestral brass section.
I can edit the properties section to remove this confusion, but I would like input from other editors and comments from readers before doing so.  Please add your comments immediately following.  Thank you.  --OhioFred (talk) 15:45, 5 January 2014 (UTC)
thread_title:  Confusion between orchestral Brass Section and Instruments Containing Brass 

message: I removed the sentence "Brass is a substitutional alloy" from the start of the third para of the introduction.
Firstly, it's not relevant to the rest of the paragraph. Secondly, I imagine that very few readers will know what it means - I'm pretty well-informed technically but I didn't know. So I think it's inappropriate for the introductory paragraph.
If someone could contribute a section about the structure of brass, it might fit in there.
