    Tungsten - Copper W - Cu Hermetic Packages Electronics Component Heat Sink

    Tungsten-Copper (W-Cu) Electronic Packing Component Heat Sink


    Copper Tungsten is one of the most popular refractory metal based heat sink materials offered today. With the new off-the-shelf system, we are able to offer standard products with a short lead-time at extremely competitive rates.

    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.


    Good machinability

    Good hermeticity

    Good thermal conductivity

    Good mechanical strength to provide excellent mechanical protection to the IC

    Molybdenum copper carriers are 40% lighter than comparable tungsten copper composite.
