Tungsten Copper for Electrical

Tungsten copper electrode for electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Our tungsten copper electrode materials are used owing to their unique physical properties.

Advantages: without other element except tungsten and copper, uniform material, low content of gas and impurity, very high burn-off resistance, excellent thermal and electrical conductivity, all necessary joining and machining processes.
