Phosphor copper brazing wire

Phosphorus copper filler metal is a kind of air self-brazing filler metal. It has lower melting point and better fluidity than phosphorus copper silver filler metal. It is widely used in the brazing of statistical copper alloy parts in refrigeration, electrical machinery, instrumentation and other industries. With the help of phosphorus self-brazing flux, the brass and bronze brazing with phosphorus copper need not be brazed with additional flux. Brazing methods include flame brazing, furnace brazing, induction brazing and resistance brazing.
