Description: Copper tube is mainly used for generators, busbar, cable, switchgear, TRAN SFOR MERS and other electrical equipment. Heat exchange, electrical conductivity and plasticity is Go od, but poor strength and hardness. Features: Fine ductility and corrosion resistance and weldability. 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. Go od thermal conductivity, used in manufacture of magnetism instruments or meters that need anti Mag netic 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. Specifications: Material: Copper Outer Diameter: 4mm / 0.15" Inner Diameter: 3mm / 0.11" Thickness: 0.5mm / 0.02" Length: 2m / 78.74" Weight: 115g(approx.)
