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

  • Higer thermal conductivity
  • Low thermal expansion
  • High arc resistance combined with good electrical conductivity

Applications

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