Tungsten Copper Alloy Heat Sink Advantages
High thermal conductivity
Excellent hermeticity
Excellent flatness, surface finish, and size control
Semi-finished or finished (Ni/Au plated) products available
It is a composite of tungsten and copper. By controlling the content of tungsten, we can design its coefficient of thermal expansion (CTE), matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Kovar, etc.
Our tungsten copper composites to be used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-powered electronic devices. With the thermal advantages of copper with the very low expansion characteristics of tungsten, tungsten copper has properties similar to those of silicone carbide, aluminum oxide, and beryllium oxide. The thermal conductivity and low expansion also make tungsten copper alloy an excellent choice even for extremely dense circuits.
