Product Description

W70Cu30 Copper Tungsten Rod Good Electrical And Thermal Conductivity

Copper Tungsten Rod is an alloy composed of tungsten and copper. The copper content of common alloy is 10%~50%. The alloy is made of powder metallurgy and has good conductivity, thermal conductivity, high temperature strength and certain plasticity. At very high temperatures, such as above 3000 ℃, the copper in the alloy is liquefied and evaporated, absorbing a lot of heat and reducing the surface temperature of the material. Therefore, this material is also called metal sweating material.

Advantages of Copper Tungsten Rod

  • It combines the advantages of tungsten and copper, and has the characteristics of high temperature resistance, arc ablation resistance, high strength, high specific gravity, good conductivity and thermal conductivity, easy processing, steam cooling, etc. Due to the high hardness, high melting point and adhesion resistance of tungsten, tungsten copper alloys are often used as projection welding and butt welding electrodes with certain wear resistance and high temperature resistance.


Applications of Copper Tungsten Rod 

  • Tungsten copper alloys are widely used, mainly for making contact points of arc ablation resistant high-voltage electrical switches, rocket nozzle throat lining, tail rudder and other high-temperature components, as well as electrodes for electrical machining, high-temperature molds and other occasions requiring high thermal conductivity and high temperature use.
