Thanks to their unique physical properties, our contact materials tungsten-copper (WCu) and copper-chromium (CuCr) have set new standards for the industry in the field of ultra high, high, medium and low voltage applications. For the near-net shape production of copper-chromium-contacts Plansee Powertech has developed a special production process.

Tungsten carbide-silver (WCAg) is another impressive material due to its combination of particularly high wear resistance, thermal conductivity and high resistance to arc erosion.
