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 use of tungsten copper

Selection of fine Copper Tungsten alloy, tungsten copper powder, soaked by class sintering process is refined, can withstand nearly 2,000 high temperature and high stress, high melting point, high hardness, resistance to burning and good adhesion resistance, electrolytic corrosion product surface finish high, high precision, low loss. Copper tungsten is widely used as a high-voltage, ultra-hydraulic switch contacts and circuit breakers, protection ring, electric upsetting anvil block material for conductive Tsui automatic submerged arc welding, plasma cutting machine nozzles, welding, welding welding head , seam welding wheel, sealed gas Mao electrode and spark electrode point, spot welding, butt welding materials.
