Coppertungsten Wikipedia
Copper tungsten materials are often used for arcing contacts in medium to high voltage sulfur hexafluoride SF 6 circuit breakers in environments that can reach temperatures above 20,000K. The copper tungsten material 39s resistance to arc erosion can be increased by modifying the grain size and chemical composition.
