Features Wide range of applications: the round copper tube can be processed by cold, hot forging to all types of semi-finished products and finished products. Copper pipe is mainly used for generators, power rails, cables, switchboards, transformers and other electrical equipment. Electrical Conductivity: the copper tube has excellent electrical conductivity and can be used in the manufacture of wires, cables, brushes (electrical) etc. The round copper pipe has fine ductility and corrosion resistance and weldability. Thermal conductivity: the copper tube has good thermal conductivity, it can be used in the manufacture of magnetism instruments or measuring instruments that need antimagnetic interference, such as compass, aviation instrument, etc., but poor strength and hardness. Wonderful plasticity: copper tube has wonderful plasticity, it is easy to work with hot and cold pressure. The copper tube can be processed into pipes, rods, wires, ribbons, plates, foils, etc. Size information: about the copper tube, outer diameter: 4 mm/0.15 inches, inner diameter: 3 mm/0.11 inches, thickness: 0.5 mm/0.02 inches, length: 2 m/78.74 inches Description: Copper pipe is mainly used for generators, bus rails, cables, switchgears, transformers and other electrical appliances. Heat exchange, electrical conductivity and plasticity are good, but poor strength and hardness. Functions: Fine ductility and corrosion resistance and weldability. The copper pipe can be processed by cold heat forging to all types of semi-finished products and finished products. Excellent electrical conductivity, the copper tube can be used in the manufacture of wires, cables, brushes (electric) etc. Good thermal conductivity, the copper pipe can used in the manufacture of magnetism instruments or gauges that require anti-magnetic interference, such as compass, flight instrument, etc. Wonderful plasticity, easy to work with under hot and cold pressure, can be processed into pipes, rods, wires, ribbons, plates, foils etc. Specifications: Material: Copper Outer diameter: 4 mm / 0.15 inches.
