Molybdenum/copper from PLANSEE (Elmet, Cunitene or Sparkal) is a powder metallurgical material produced by the means of infiltration with copper contents from 10 to 40 %. molydenum/copper materials are infiltrated back-cast with copper and can be joined by welding or brazing with various supporting materials. PLANSEE offers MoCu as infiltrated or rolled to sheet material and foils.
Advantages of Molybdenum-copper:
- high arc resistance combined with good electrical conductivity
- high thermal conductivity
- low thermal expansion
- back-castable with copper
Typical areas of application:
- arcing contacts in high and medium voltage breakers for transmission and distribution of electrical power
- base plates or heat sinks as passive cooling elements of electronic devices
- erosion electrodes for EDM made of Sparkal
- electrodes for various applications such as surge protection, welding, brazing and laser applications
