Features Fine ductility, corrosion resistance and weldability.Can be made into all kinds of semi-finished and finished products by cold and hot forging. Wonderful plasticity, easy to machine under hot and cold pressure, can be transformed into tube, rod, wire, tape, tape, plate, sheet, etc. Excellent electrical conductivity, used in the manufacture of wires, cables, (electric) brushes, etc. Good thermal conductivity, used in the manufacture of magnetism instruments or counters which require anti-magnetic interference, such as compass, aviation instrument, etc. This copper tube is mainly used for generators, busbars, cables, switchgear, transformers and other electrical equipment. Heat exchange, electrical conductivity and plasticity are good, but their strength andhardness are poor.
