They are forged and knitted, and in many cases the seams of them are as strong as the metals to be soldered. Solder PSr-10 contains 10% silver - practically the smallest amount in solder for hard soldering. It can be used for joining parts made of steel and non-ferrous alloys that heat up during operation to a temperature of 800 ° C, such as, for example, for brazing primus burners. Its use is expedient when the parts are subsequently subjected to heat treatment at relatively high temperatures, which, however, do not exceed the melting temperature of the solder. Solder PSr-12 is used for brasses with a copper content of 58% and more. For delicate work, when special cleanliness of the junction is required, PSr-25 solder is used. However, the seam from PSr-25 does not withstand shock loads well and gives cracks in butt joints. Therefore, the joints of parts up to 3 mm thick are more reliable to connect with PSr-45 solder, which contains much more silver than the previous ones. It can be used to solder copper, bronze, steel and nickel parts. This solder is yellowish, viscous, fluid, and good corrosion resistance. The seam from it withstands shock and vibration well. Solder PSr-65 is used for soldering band saws, and PSr-70 is used for soldering wires in cases where it is important that the junction points do not sharply decrease the electrical conductivity. Manufacturers usually supply the silver solder in sheets, which are then cut into strips of the required size. A piece of solder obtained by fusion is rolled on rollers to a sheet thickness of 1.5-2 mm (or thinner, depending on the soldering method), and then cut into strips. The extreme (wider) strips with uneven edges, resulting from sheet rolling, are used when soldering large parts (with a long seam), where a lot of solder is needed. The short rods remaining after soldering, which can no longer be held by hand, are soldered to other rods or to brass wire in order to use them to the end. For joining small thin parts requiring a small amount of solder, it is recommended to use strips 0.5–3 mm wide.
