The products are an alloy of tungsten and copper or silver made through the above process.
The standard composition is 75/25% (tungsten/copper or -/silver) although other compositions
are available. The shape of product are available to be provided in rod, plate and cut pieces
1. 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 and adherence resistance.
It is used for projection welding and butt-welding electrode with high temperature resistance.
2. Electric spark electrode
It is used for the electrode of mould made from tungsten steel alloy and mega-hard alloy.
The common electrode has high consumption and low rate.
The high electrical ablation rate, low consumption ratio, precise electrode size and high quality
processing performance of copper tungsten can ensure that the precision of the work piece
is greatly enhanced.
3. High-voltage discharge tube electrode
When the high-voltage vaccum discharge tube is working, the temperature of contact material
will rise to thousands degreed centigrade within several tenths seconds.
High ablation resistance, high toughness, good electrical and conductivity of copper tungsten
provide necessary condition to stable operation of the discharge tube.
4. Electric contact
a) Telecommunication
b) Control signal
c) Automotive & Power relay
d) Semi-conductor
e) Weight balance
f) Electric connector - conductive device joining & electric circuit breaker together
Electrode contact can be produced from a variety of precious metal material including
fine silver, silver tungsten, copper tungsten and copper graphute alloy.
Mainly, the application have been widely used in mechanical switchs and circuit breaker.
Many kind of them required high quality and safety for electric,thermal shock for each process. |
