Cu - W Heat Spreader Material CuW Electronic Thermal Management Materials


Cu-W Heat Spreader Material for Ceramic Packages CuW Electronic thermal management materials

Description:

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.
It is an composite 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
