ASME SB280 Copper Alloy C12000 Seamless Tube

Oct 09, 2025 ASTM-B280-Copper.pdf

Copper C12000 is a phosphorus-deoxidized copper with a limited, medium amount of residual Phosphorus. It has good electrical conductivity and excellent welding and soldering properties. It can be formed excellent, either hot or cold. Copper C12000 has 95 percent IACS conductivity, low residual phosphorus, and high embrittlement resistance. Forging of UNS C12000 copper can be performed at a temperature of about 760 to 871 degrees C (1400 to 1600 degrees F). Copper C12000 Tubes have good forgeability, low machinability, and excellent hot and cold working capacity.

 

UNS C12000 Copper Tubes are widely used for heat exchangers, radiators, coolers, electro-heat-up pipes, air conditioners, refrigerators, oil transportation, brake pipes, water pipes, and gas pipes for construction, bus bars, and electromechanical hardware connectors.

Application

Copper plates are mainly used in electrical conductivity, heat conduction, and corrosion-resistant equipment. For instance, they

are applied in wires, cables, conductive screws, blasting detonators, evaporators for chemical industries, storage containers, and

various pipelines, etc. They can also be used as force-bearing parts for various deep drawing and bending manufacturing processes,

such as pins, rivets, washers, nuts, conduits, pressure gauges, screens, and radiator parts, etc.
