Copper Tungsten

This refractory metal composite materials are a combination of tungsten combined with copper or silver. The manufacturing process is to press the refractory, sinter the pressed compact at a high temperature, and infiltrate with copper or silver. All this is done under very closely controlled conditions. The result is a relatively hard materials with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.


Advantages:
- Higher thermal conductivity
- Low thermal expansion
- High arc resistance combined with good electrical conductivity


Applications:
- Heat Sinks as passive cooling elements of electronic devices
- Electrodes for resistance welding
- Electrodes in electric spark erosion cutting machines
- Arcing contacts and vacuum contacts in high and medium voltage breakers or vacuum interruptions
