Copper tube is mainly used for generators, busbar, cable, switchgear, transformers and other electrical equipment. Heat exchange, electrical conductivity and plasticity is good, but poor strength and hardness. Features: Fine ductility and corrosion resistance and weld ability. Can be made into all kinds of semi-finished products and finished products by cold, warm forging. Excellent electrical conductivity, used in manufacture of wire, cable, brush(electric), etc. Good thermal conductivity, used in manufacture of magnetism instruments or meters that need anti magnetic interference, such as compass, aviation instrument, etc. Wonderful plasticity, easy to machining under hot and cold pressure, can be made into tube, rod, wire, strip, belt, plate, foil, etc. Specification: Material: T2 Copper Outer Diameter: 6mm / 0.23inch Inner Diameter: 4mm / 0.15inch Thickness: 1mm / 0.04inch Length: 2m / 6.6ft Weight: Approx. 275g / 9.7oz Package List: 1 x Copper Tube Note: 1.
