W70Cu30 Copper Tungsten Edm Electrodes High Melting Point
Tungsten Copper ( CUWU, WCU) alloy is a pseudo-alloy of tungsten and copper. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite than a true alloy. Copper tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant,ablation-resistant, highly thermally and electrically conductive, and easy to machine.

Features
Tungsten-copper alloy has a wide range of applications, most of which are used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment, and other industries. Secondly, it is also used to manufacture the contacts of high-voltage electrical switches and high-temperature components such as rocket nozzle throat liner and tail rudder, which are resistant to arc erosion, and also used as electrodes for electrical machining, high-temperature molds and other occasions requiring conductive and thermal conductivity and high-temperature use.
Applications
1. Arcing contacts and vacuum contacts in high and medium voltage breakers or vacuum interrupters
2. Electrodes in electric spark erosion-cutting machines
3. Electrodes for resistance welding.
