Silver based brazing Flux Powder Silver based brazing material is a kind of alloy brazing material mainly composed of silver or silver based solid solution. It can be used to braze almost all ferrous and non-ferrous metals except aluminum, magnesium and other low melting point metals. Silver based solder is widely used in vacuum electronic components, refrigeration, medical, electronics, motor, electrical appliances, instruments, jewelry and other industries. Silver based active brazing materials are widely used because of their excellent wettability to diamond, graphite and carbon products, cubic boron nitride, alumina and other ceramic materials.
