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. Your contact …

Copper–tungsten - 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's resistance to arc erosion can be increased by modifying the grain size and chemical composition.

Carbide - Wikipedia

The carbides of the group 4, 5 and 6 transition metals with the exception of chromium are often described as interstitial compounds. These carbides have metallic properties and are refractory.Some exhibit a range of stoichiometries, being a non-stoichiometric mixture of various carbides arising due to crystal defects.Some of them e.g. titanium carbide, TiC and tungsten carbide are important ...
