They are composites of tungsten and copper. So both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized.
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.
Used as Thermal mounting plates,chip carriers,flanges, frames for RF and substrates etc.
1.High thermal conductivity
2.Excellent hermeticity
3.Excellent flatness, surface finish, and size control
4.Semi-finished or finished (Ni/Au plated) products available
