Molybdenum-Copper Heat Sinks

molybdenum copper heat sinksThey 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. Here is what our customers say about us!

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
