Tungstencopper 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. Your contact Person for:

Coppertungsten Wikipedia

When the contact is very fine grained VFG , the electrical conductivity is much higher than a normal piece of copper tungsten. 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.
