Silver brazing filler metals have low melting point, good wettability and filling performances. They also have features of high mechanical strength, fine plasticity, electrical conductivity and corrosion resistance.
The filler metals are used in the brazing of stainless steel, carbon steel, hard alloys, copper and copper alloys, etc. In order to meet some specific needs in the brazing process, indium, tin or nickel can be added to compose quaternary alloys or complex alloys. Flux is usually applied to achieve the desired joints.
