Product Description

Tungsten Copper Bar, Elkonite® ASTM B702 RWMA Class 10,Class 11, Class 12

 

The tungsten copper bar is an alloy composed of tungsten and copper, and the copper content of the commonly used alloy 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 3000C, the copper in the alloy is liquefied and evaporated.

 

  • Description

The tungsten copper bar is an alloy composed of tungsten and copper, and the copper content of the commonly used alloy 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 3000C, 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 bar grade: WD10070;
Model: 55W45Cu, 68W32Cu, 70W30Cu, 75W25Cu, 80W20Cu, 85W15Cu, 90W10Cu.
