Features Good thermal conductivity, used in the manufacture of magnetism instruments or measuring instruments that need anti-magnetic interference, such as compass, aviation instrument, etc. Can be processed by cold-hot forging into all types of semi-finished products and finished products. Excellent electrical conductivity, used in the production of wires, cables, brushes (electric), etc. Wonderful plasticity, easy to work with under hot and cold pressure, can be processed into pipes, rods, wires, tapes, plates, films, etc. Fine ductility and corrosion resistance and weldability. Description: Copper tube is mainly used for generators, busbars, cables, switchgear, transformers and other electrical equipment. Heat exchange, electrical conductivity and plasticity are good but poor strength and hardness. Specifications: Material:CopperOuter Diameter:4mm/0.15" Inner diameter: 3 mm / 0.11 inches.
