    Low CTE Copper Tungsten Alloy Electronic Packaging Materials WCu Heat Sink

    Low CTE Copper Tungsten Electronic Packaging Materials WCu Heat Sink


    CuW, also called copper tungsten, tungsten copper and W-Cu, is a powdered metal product consisting of a mixture of copper and tungsten (a.k.a. wolfram).

    Our heat sink are composites of tungsten and copper. By adjusting the content of tungsten, we can have its coefficient of thermal expansion (CTE) designed to match those of materials such as ceramics (Al2O3, BeO), semiconductors (Si), and metals (Kovar), etc.


    High thermal conductivity

    Excellent hermeticity

    Excellent flatness, surface finish, and size control

    Semi-finished or finished (Ni/Au plated) products available

    Product Properties:

    at 20ºC
    Thermal conductivity at 25ºCCoefficient of thermal expansion at 20ºC


    Applies to high-power device package of materials, such as substrates; high-performance lead frame; military and civilian thermal control devices such as thermal control panels and radiators.
