What is Tungsten Copper

Tungsten copper is composed of tungsten and copper, and its use is relatively wide. It is a kind of alloy made by exquisite soaking sintering process and the content of copper is 10% ~ 50%, it not only has good conductivity and thermal conductivity, but also has high melting point and hardness, resistance to burning and good adhesion. Besides, it has good heat resistance and plasticity, low loss, high precision and high surface finish.

Tungsten copper is widely used in electric welding machine, the welding head of welding machine, welding roller, sealing gas electrode, spark electrode and welding materials. It also used in the electric heating pier coarse block materials, automatic submerged arc welding conductive nozzle and plasma cutting machine nozzle. Sometimes used as a high pressure and super hydraulic switch, breaker contact and guard ring.

At higher temperature, such as 3000 degrees Celsius, the copper in the alloy is liquefied. A large amount of heat in copper is absorbed and reduces the surface temperature of the material. Therefore, it also called metal sweat material.

Because tungsten and copper are not miscible, tungsten copper has high conductivity and thermal conductivity of copper, wear resistance, low expansion and corrosion resistance of tungsten, it also suitable for all kinds of machining. Tungsten copper can be based on user requirements to complete the production and size processing of tungsten copper. Process of powder metallurgy of it is flour mix proportioning and pressing forming.
