Application:

Because of the high electrical conductivity and low consumption, Copper tungsten bars are widely used to make Grid siderod, Lead,Support, and Electrode for the Gas discharge lamp.

Resistance welding electrode
It integrates such features of tungsten and copper as high temperature resistance, electrical arc ablation resistance, high proportion, good electrical and heat conductivity, being easy to cut and transpiration cooling. It also owns such advantages of tungsten as high hardness, melting point and adherence resistance. It is often used for projection welding and butt-welding electrode with wear and high temperature resistance.

Electric spark electrode
It is used for the electrode of mould made from tungsten steel and high-temperature and ultra hard alloy. The common electrode has high consumption and low rate. The high electrical ablation rate, low consumption ratio, precise electrode size and quality processing performance of Copper tungsten can ensure that the precision of the work piece is greatly enhanced.

High-voltage discharge tube electrode
When the high-voltage vacuum discharge tube is working, the temperature of contact material will rise to thousands degree centigrade within several tenths seconds. High ablation resistance, high toughness, good electrical and heat conductivity of Copper tungsten provide necessary conditions to stable operation of the discharge tube.
