Copper tube is mainly used for generators, busbars, cables, switchgear, transformers, and other electrical equipment. It has good heat exchange, electrical conductivity, and plasticity, but lower strength and hardness. Features: Excellent ductility, corrosion resistance, and weldability. Can be formed into various semi-finished and finished products through cold and warm forging. Offers high electrical conductivity, suitable for manufacturing wires, cables, electric brushes, and similar components. Good thermal conductivity makes it ideal for magnetic instruments or meters requiring anti-magnetic interference properties, such as compasses and aviation instruments. Possesses excellent plasticity and is easy to machine under both hot and cold pressure conditions. Can be processed into tubes, rods, wires, strips, belts, plates, foils, and more.
