Features Good ductility: good ductility and corrosion resistance and weldability. [Easy to work with]: various semi-finished and finished products can be made by cold and hot forged. [Excellent Conductivity]: excellent conductivity, used in the manufacture of wires, cables, brushes (electricity) etc. [Good thermal conductivity]: Good thermal conductivity, used to make magnetic instruments or counters that require anti-magnetic interference, such as compass, aviation meter, etc. [Plasticity]: excellent plasticity, easy to work with hot and cold pressure, can be transformed into pipes, rods, wires, strips, plates, leaves, etc. Description: The copper tube is mainly used for generators, rod sets, cables, switching equipment, transformers and other electrical equipment. The heat exchange, electrical conductivity and plasticity are good, but the strength and hardness are poor. Features: Material: copper, outer diameter: 4 mm. Inner diameter: 3 mm. Thickness: 0.5mm Length: 2m Weight: approx. 115g Box contents: 1 x Copper Tube Note: 1. Please allow 1-3 cm error due to manual measurement. Thank you for your understanding. 2.
