Copper tungsten materials,Copper Tungsten Electrical Contacts,WCu Electrode material

Tungsten copper alloy is an alloy of tungsten and copper. Commonly used copper content of the alloy is 10% to 50%. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, the alloy of copper is liquefied and evaporated to absorb a lot of heat, reducing the surface temperature. So this kind of material is also referred to as metal sweat material.

The main purpose of copper-tungsten alloy

Copper Tungsten alloy is mainly used in:
1. electrode materials: for high hardness materials and flake, electrical discharge machining, EDM product surface finish, high precision, low loss, effective conservation.
2. Contact Material: High pressure switch or circuit breaker arcing contacts and vacuum contacts, circuit board welding and electrical contact points.
3. Welding Material: submerged arc welding machine, gas shielded welding tip, radio resistor factory (production of carbon film resistors, metal coating resistance) Resistance Welder Welding materials (Copper Tungsten alloy

welding disc).

4. guides materials: wire rod mill, for guiding the protective effect of the material.
