Details

High silver brazing alloy is composed of silver or silver based alloy. It has perfect welding effect with low melting point fine wet ability and extensive flow property. For its high strength & good plasticity & good electric conductivity and corrosion resistance, it can be used for welding all kinds of ferrous and non-ferrous metals except aluminum & magnesium and other low melting point metals
