Copper Brazing Alloy

Sanhuan Welding phosphor-copper brazing alloy is a binary alloy based on copper and phosphorus. It features excellent flowability, affordability, and good workability. This brazing alloy is suitable for resistance welding, gas flame brazing, high-frequency brazing, and certain furnace brazing applications, producing joints with good strength.

Sanhuan phosphor-copper-tin brazing alloy has a black color, a low melting point, and good brittleness. It exhibits excellent wettability, flowability, spreadability, and gap-filling capabilities. By adding an appropriate amount of tin (Sn) to the phosphor-copper alloy, the melting point is reduced, and flowability and wettability are improved, which also results in the brazing alloy’s black color.
