2022 Hot Sale Tungsten Copper W70cu30 Rod Bar Price
Product Description
Tungsten copper rod is an excellent electrode material for precision EDM, resistance welding and plasma spraying applications. Copper tungsten is a high-strength composite material composed of 70/30 copper and tungsten. It combines the electrical conductivity of copper with the heat resistance and wear resistance of tungsten. Generally speaking, the special properties of tungsten copper rods are very suitable for applications that require high temperature resistance, electrical corrosion resistance, high thermal conductivity and low thermal expansion.
Tungsten copper alloy (WCu) is composed of high melting point, high hardness tungsten and high electrical conductivity, high thermal conductivity copper, so it has the advantages of heat resistance, ablation resistance, high thermal conductivity, high strength, high hardness and so on. It is widely used in electrical contact materials for high-voltage switches such as vacuum, resistance welding electrode materials, electronic packaging materials, heat sinks, and radiation shielding materials. Materials for electric upsetting anvils, contact tip automatic submerged arc welding, plasma cutting nozzles, welding machines, welding heads for welding, seam welding wheels, welding rods and spot sealing gas-filled spark welding rods, spot welding, butt welding materials, etc.
