Tungsten Copper

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

1. Higer thermal conductivity
2. Low thermal expansion
3. High arc resistance combined with good electrical conductivity

Applications

1. Electrodes for resistance welding
2. Heat sinks as passive cooling elements of electronic devices
3. Electrodes in electric spark erosion cutting machines
4. Arcing contacts and vacuum contacts in high and medium voltage breakers or vacuum interruptions
