Features Fine ductility and corrosion resistance and weldability Can be processed into all kinds of semi-finished products and finished products by cold and hot forging Excellent electrical conductivity, used in the production of wires, cables, brushes (electric), etc Good thermal conductivity, used in the manufacture of magnetism instruments or meters Wonderful plasticity, easy to work under hot and cold pressure Description: Copper tube is mainly used for generators, busbars, cables, switchboards, transformers and other electrical equipment. Heat exchange, electrical conductivity and plasticity are good, but poor strength and hardness.
