Copper Phosphorus Alloy

Copper Phosphorus (CuP) Alloy is an alloy made from copper being deoxidized with phosphorus. This is the most commonly used deoxidized copper. This master alloy is used as a deoxidant and alloying agent in the copper industry and also has applications in the aluminum, bronze, and brass industry. Copper is corrosion-resistant, but this property becomes enhanced with added phosphor. There is an increase in tensile strength, a reduction in brittleness characteristics, and an improvement in machinability and workability with the phosphorus addition to copper.

Reade offers one grade for the aluminum industry and three grades for the copper industry.
Typical Applications

Copper Phosphorus alloy is used as a deoxidant, alloying agent, and wetting agent for the copper industry, and also has application as a nucleant for the aluminum industry.
