Copper tungsten and copper tungsten carbide offer low-cost alternatives to silver tungsten and silver tungsten carbide when used in non-oxidizing conditions. Vacuum as well as oil and gas filled devices often use copper tungsten contacts. In air, the material is frequently used for arcing contacts or where there is sufficient contact force to break through the oxides that are inevitably formed.

Copper–tungsten - Wikipedia

Copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding. CuW is usually a contact for vacuum, oil, and gas systems. It is not a good contact for air since the surface will oxidize when exposed. CuW is less likely to erode in air when the concentration of copper is higher in ...

Tungsten-copper WCu Plansee

Tungsten copper WCu materials are used for arcing contacts in SF 6 circuit breakers for high and medium voltage appli ions. At the heart of the switching chamber, WCu arcing contacts are exposed to extreme mechanical and thermal stresses. During arcing, the temperature can reach levels ≥ 20,000 K, for instance.
