The requirements towards high performance materials, often can not be fully satisfied with properties of only one metal or alloy. In that case material compounds of metals which are insoluble with each other form a basis to fulfil extreme requirements. Material compounds are produced using the technology of back-casting with molten copper.
Example: A material compound of tungsten (highest melting point) and copper (high thermal and electrical conductivity) brings together high arc resistance with extreme cooling capability. As tungsten is insoluble in copper, the typical properties of both metals, tungsten and copper, can be combined in one material and open-up wide fields of applications.
Advantages of metallic material compounds:
- high arc resistance combined with good electrical conductivity
- high thermal conductivity
- highest thermal resistance
- good machinability
Typical applications of PLANSEE material compounds:
- stationary anodes
- plasma spray nozzles and electrodes
- arcing contacts
