Tungsten Copper Alloy Welding Electrodes Description
Tungsten Copper Alloy Welding Electrodes For EDM Welding is used when a product or part needs to have high heat resistance, low thermal expansion, and high electrical or thermal conductivity. Tungsten copper alloy is used to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts, and electrical contacts are all made out of tungsten copper alloy. The alloy is also made into sheet metal, tubing, and plate metal. Tungsten copper alloy is used to make contacts for both high and low voltage electrical devices, and for high-speed steel devices and switches.
