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