Tungsten copper refers to an alloy composed of tungsten and copper. The copper content of common alloys is 10% to 50%. The alloy is prepared by powder metallurgy method and has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above , the copper in the alloy is liquefied and evaporated, which absorbs a large amount of heat and lowers the surface temperature of the material.
So this type of material is also known as metal sweating material.Tungsten-copper alloys have a wide range of applications, mainly for the manufacture of high-voltage electrical switch contacts for arc ablation and high-temperature components such as rocket nozzle throat linings and tail rudders, as well as electrodes for electromachining, high temperature molds and others. Where electrical and thermal conductivity and high temperature use are required.
Tungsten copper is made of fine tungsten and copper powder. It is refined by first-class soaking and sintering process. It can withstand high temperature and high stress of nearly 2000 degrees. It has high melting point, high hardness, anti-burning and good anti-adhesion.
Surface roughness of electroerosion products High, high precision and low loss.Tungsten copper is widely used as a high voltage, super hydraulic switch and circuit breaker contact, protection ring, for electric heating pier coarse anvil material, automatic submerged arc welding conductive nozzle, plasma cutting machine nozzle, electric welding machine, butt welding machine welding head , welding wheel, gas sealing electrode and point spark electrode, spot welding, welding materials.
