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.
