High Electric Conductivity W75Cu Plate With Hardness 195HB For Resistance Welding
Tungsten Copper Alloy Plate Introduction:
Tungsten and copper are made from fine tungsten and copper powder by immersion sintering process, which can withstand high temperature and high stress of nearly 2000 degrees. They have high melting point, high hardness, ablation resistance and good adhesion resistance. The finished surface of tungsten copper alloy plate has high precision and low loss.

Tungsten Copper Alloy Plate Applications:
Tungsten copper alloy has a wide range of applications, mainly used to manufacture high-temperature components such as contacts of high-voltage electrical switches, nozzle throat liners and tail rudders that are resistant to arc ablation, and also used as electrodes for electrical machining, high-temperature molds and other occasions requiring conductivity and heat conductivity and high-temperature applications.
When the tungsten copper alloy plate is used for the electrode of the high-voltage discharge tube, when the high-voltage vacuum discharge tube is working, the temperature of the contact material will rise by thousands of degrees Celsius in a few tenths of a second, while the ablation resistance, high toughness, good conductivity and thermal conductivity of tungsten copper provide necessary conditions for the stable operation of the discharge tube.
We also offer tungsten copper alloy rings, plates, spare parts, etc..
