What Is Tungsten Copper Contact

Tungsten copper contact is 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 alloy electrode materials are used because of tungsten copper alloy electrode unique physical properties. Tungsten copper alloy electrode material offered by us is high quality. We can provide all kinds of tungsten copper electrode as your requirements. Tungsten copper electrode is easy to be machined.
