Coppertungsten 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 ...
