Copper phosphorus alloy is a type of copper and phosphorus material predominantly found in welding applications. Phosphor bronze solder is a solder made from a two-component copper-phosphorus alloy. It features good liquidity and can be used for contact brazing, flame brazing, high-frequency brazing, and oven brazing. Introducing silver into the phosphor copper alloy will significantly boost the wettability of the solders; increase their strength and ductility; and decrease their melting points. It has wide applications such as refrigeration industry, motor manufacturing industry, electrical appliance manufacture industry, instrument manufacturing industry etc. Copper-zinc solder is mostly used in flame, high frequency and resistance methods of brazing.
