Heat-resistant Material with High Conductivity

These alloys combine tungsten’s exceptional thermal resistance with copper’s outstanding thermal and electrical conductivity. By adjusting the chemical composition, key properties such as conductivity, thermal expansion, and burn-off behavior can be precisely tuned to meet specific requirements.

Applications include electrical switching contacts, EDM electrodes, and heat sinks for power electronics, anywhere thermal stability and conductivity are critical.

SVS Capabilities

Key Features

Advantages of the Tungsten-Copper Combination

  • Optimized Heat Conductivity

    Copper ensures excellent heat and electrical conductivity, while tungsten contributes high-temperature resistance.

  • High Thermal Stability

    The high melting point of tungsten helps the material retain its mechanical integrity at extreme temperatures.

  • Low Thermal Expansion

    A low coefficient of thermal expansion maintains dimensional stability under thermal cycling.

  • Good Machinability

    Despite tungsten’s inherent hardness, the copper content enables cost-effective shaping and machining.
