6. circuit breakers. 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.

Coppertungsten 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 materials resistance to arc erosion can be increased by modifying the grain size and chemical composition.

Electrical Contacts are made from a Variety of Materials

Copper tungsten and copper tungsten carbide offer lowcost alternatives to silver tungsten and silver tungsten carbide when used in nonoxidizing conditions. Vacuum as well as oil and gas filled devices often use copper tungsten contacts. In air, the material is frequently used for arcing contacts or where there is sufficient contact force to ...


Manufacture of Tungsten Copper and other sintered materials is a natural augmentation to its primary business of Chromium Copper and Beryllium Copper. Synergy in appli ion of these materials has now made Mipalloy an undisputed leader in several fields of engineering including electrical, automobile, metallurgy and fabri ion.

The copper tungsten grades for contact metals are Vaculoy CT60, CT70, CT75, CT78 and CT80. This range of compositions will cover most appli ions for acing contacts in air blast, oil immersed and SF6 gas circuit breakers. The higher the conductivity grade Vaculoy CT60 is also for onload tapchanger contacts operating in oil.


Tungsten Copper is used for ECM electrodes because it conducts high current and resists deformation and abrasion from the high velocity movement of the electrolyte. RESISTANCE WELDING High hardness and high strength at elevated temperatures and good electrical and thermal conductivities make these materials particularly suited for resistance welding electrodes.
