Tungsten copper (WCu) alloy is a composite material that combines the thermal conductivity benefits of copper with the low thermal expansion properties of tungsten. By adjusting the tungsten content, its thermal expansion can be tailored to match materials such as silicon (Si), aluminum oxide (Al2O3), and beryllium oxide (BeO). Typically, the copper content ranges from 10% to 50%. This material has high density, excellent heat dissipation, high-temperature strength, and resistance to erosion.
WCu alloy offers the combined advantages of both tungsten and copper: it has good resistance to high temperatures and arc erosion, high strength, high density, good electrical and thermal conductivity, and low thermal expansion. Additionally, it is easy to machine. This makes it widely used in applications such as electrodes for resistance welding and electric spark erosion cutting machines, as well as arcing contacts and vacuum contacts in high and medium-voltage breakers or vacuum interrupters.
