Copper Phosphorus Solder

Copper-phosphorus solder is an alloy solder with copper and phosphorus as the main elements. It has good fluidity during brazing, low brazing temperature and self-brazing effect. When welding pure copper, it can be welded in a normal atmosphere without flux , Suitable for welding methods such as resistance brazing, flame brazing and induction brazing of copper and copper alloys. Because phosphorus easily forms brittle compounds with iron, copper-phosphorus brazing filler metal is not recommended for brazing ferrous metals.
