Silver brazing filler metals is universal alloy brazing materials, used for brazing black and nonferrous metal materials (steel, brass, copper, etc.), brazing process in addition to the vacuum brazing furnace and other welding methods need to cooperate with silver brazing agent to achieve good welding effect, part of the silver based solder tin was added to reduce the melting point of the solder.

Silver cadmium containing brazing filler metal with high humidity resistance, good fluidity and melting point in all silver based solder minimum, but cadmium and cadmium oxide is toxic, welding process must have special protection measures, such as excellent row wind system and the protection cover.
