Tungsten Copper Dies

Home / news / Tungsten Copper Dies

Tungsten Copper is a composite alloy of copper and tungsten produced by powder metallurgy, containing from 10 to 70 weight percent of copper. This product is usually used for contact points of switches and circuit breakers filled with oil or SF6 gas.

ON/OFF of electric current is one of the most important functions of electric switches. For this purpose, a composite material of copper or silver having a good electric conductivity and tungsten with little arcing wear is used for the contact of switches. Because of having advantages of little thermal expansion, good thermal conductivity and large specific gravity, our contact materials are applied to various purposes other than the contact.

For this dies are made of tungsten copper,material:EME-C30A2 / RWMA-11 which contains 30% Cu 70% W.Which used for hot punching steel plate and need conduct electricity.
