High silver brazing alloy is composed of silver or silver based alloy. It makes perfect welding effect with low melting point, fine wettability and extensive flow property. For its high strength, good plasticity, electric conductivity, well corrosion resistance, it can be used for welding all ferrous and nonferrous metals except of Aluminum, Magnesium, and other low melting point metals.
