Low CTE Copper Tungsten Electronic Packaging Materials WCu Heat Sink

Description:

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.


Advantages:

High thermal conductivity

Excellent hermeticity

Excellent flatness, surface finish, and size control

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