Physical Properties of C10100
C10100 copper alloy has a density of 8.96 g per cubic centimeter and a melting point of 1083 degrees C. Its electrical conductivity is superior to silver and second only to gold among metals in practical engineering use, and it has excellent corrosion resistance in atmospheric, freshwater, and seawater environments.
Other Designations
C10100 is known by many designations including 101 OFEC, C101, CA 101, CDA 101, OFE 101, OFEC, OFE Copper, OFE Cu, and Electronic Grade Copper. According to GB/T 5231-2012, the most equivalent Chinese grades are TU0 and TU1, which are also high-purity oxygen-free coppers.
Application Areas
In the electrical industry, C10100 is widely used in the manufacture of wires, cables, and motors because of its excellent electrical conductivity. In construction, it is used for roofs, walls, doors, and windows, where its corrosion resistance and aesthetic appeal are valued by architects. In the chemical industry, it is used in pumps, valves, and pipelines that withstand corrosive media such as acids and alkalis. In coinage, it is used for its good wear resistance and anti-counterfeiting properties.
Machinability and Weldability
C10100 has excellent cold and hot workability and high ductility, making it suitable for rolling, drawing, and forging. However, its high ductility can lead to gummy chips during machining. It has excellent weldability, with electron beam welding and gas-shielded arc welding commonly used, and its thermal conductivity nears the theoretical maximum for copper.
Seamless Tube Manufacturing Process
C10100 seamless tube is manufactured through a controlled sequence: melting, casting, extruding, drawing and pilgering, cutting, inspection, annealing, and packing. Each stage is monitored to preserve purity and dimensional accuracy.
