Tungsten Copper Alloy Ring

Tungsten copper alloys are mainly used for producing high-temp components like arc-ablation resistant high voltage electrical switches and rocket nozzle throat linings, and tail rudders. As well, tungsten copper alloys serve as electrodes for electrical discharge machining, high-temperature moulds, and other applications that require high electrical and thermal conductivity and high temperature.
