PLANSEE copper-chromium composite materials possess a chromium content up to 60 %. The precipitation-harded condition exhibits optimized mechanical properties in comparison to pure copper even at elevated temperatures.
Advantages of CuCr:
- low contact resistance combined with low arcing
- high hot strength
Typical areas of application of CuCr:
- contacts in vacuum circuit breakers for medium voltage breakers for the distribution of electrical power
