Molybdenum-Copper Heat Sinks
They are composites of molybdenum and copper. Similar to W-Cu, CTE of Mo-Cu can also be tailored by adjusting the content of molybdenum. Mo-Cu is much lighter than W-Cu so that it is suitable for aeronautic and astronautic applications.
Our products are widely used in applications such as optoelectronics packages, Microwave Packages, C Packages, Laser Submounts, etc.
Advantages
- High thermal conductivity since no sintering additives have been used
- Excellent hermeticity
- Relatively small density
- Stampable sheets available (Mo content no more than 75 wt%)
- Semi-finished or finished (Ni/Au plated) parts available
