Key Material Properties
Thermal Conductivity
With its high copper content, the alloy ensures effective thermal conductivity. It performs reliably in systems with localized heating or heat-sensitive elements.
Thermal Stability
The tungsten content provides dimensional stability under thermal load.
Thermal Expansion
The combination of tungsten and copper offer defined thermal expansion, minimizing internal stress under fluctuating temperatures.
Machinability
The material is easier to machine than pure tungsten, supporting complex part geometries and tight tolerances while reducing production effort.
Fields of Application
Examples of Use
Tungsten-copper alloys are used wherever high currents, thermal stress and tight tolerances must be managed simultaneously. They are commonly used in electrical components such as high-current contacts, circuit breakers and transistors. Their high thermal conductivity prevents heat accumulation and supports safe switching under load.
In welding and cutting technology, tungsten-copper materials are used as electrodes for plasma cutting and electrical discharge machining (EDM). Their temperature resistance and dimensional stability contribute to consistent and precise processing results.
In aerospace applications, they are used in plasma electrodes, thermal protection systems and structural components that must remain dimensionally stable under extreme temperature and pressure conditions.
