Cu-W Heat Spreaders For Use In Cellular Base Stations And Optical
Communications
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.
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

| 85WCu | 85±2% | 16.4 | 7.2 | 190 (25℃) / 183 (100℃) |
| 80WCu | 80±2% | 15.65 | 8.3 | 200 (25℃) / 197 (100℃) |
| 75WCu | 75±2% | 14.9 | 9.0 | 230 (25℃) / 220 (100℃) |
| 50WCu | 50±2% | 12.2 | 12.5 | 340 (25℃) / 310 (100℃) |
Application:
These composite are widely used in applications such as
Optoelectronics Packages, Microwave Packages, C Packages, Laser
Sub-mounts, etc.
