Chung Metal provides Copper C10940 Bars and Rods, a phosphor-deoxidized copper alloy with enhanced corrosion resistance and weldability. C10940 contains more phosphorus than regular deoxidized copper, making it highly workable in hot or cold conditions. It is used in water plumbing systems, heating, ventilation, and air conditioning equipment, and fabrication operations involving brazing or welding. Our C10940 rods and bars are resistant to mechanical stress and withstand long-time exposure in water or moist environments.
C10940 generally has ~99.5% copper and ~0.04–0.06% phosphorus. Tensile strength is ~200–280 MPa; yield strength ~70–110 MPa; elongation about 30–45%. The conductivity is ~85–90% IACS. Phosphorus content increases the oxidation resistance as well as inhibits embrittlement when brazing or welding. It retains structural integrity against thermal cycling.

Yes, Copper C10940 Bars and Rods can be susceptible to galvanic corrosion when in contact with dissimilar metals, particularly in the presence of an electrolyte. Proper insulation or coatings help prevent this.
Yes, Copper C10940 Bars and Rods are fully recyclable. The material retains its key properties after recycling, making it an environmentally sustainable option for industrial use and reducing waste.
Yes, Copper C10940 Bars and Rods can be used for natural gas applications. They offer excellent corrosion resistance and conductivity, but additional protection may be needed in harsh or high-pressure environments.
C10940 Bars and Rods find application in hot water applications, brazed construction, electrical terminals, fittings, tubing, and industrial plumbing. It is best suited for HVAC equipment, refrigeration devices, and solar water heaters. Because it is resistant to hydrogen embrittlement, it’s frequently employed in gas distribution and heating systems. Its formability and weldability make it a good fit for architectural, construction, and appliance parts.
