Molybdenum-Copper for Heat Sinks

Molybdenum Copper heat sinks is a composite made from Mo and Cu, Similar to W-Cu, CTE of Mo-Cu can also be tailored by adjusting the composition. But Mo Cu is much lighter than W-Cu, so that it is more suitable for aeronautic and astronautic applications.

Advantages:?High thermal conductivity due to no sintering additives was used;

Excellent hermeticity;

Relatively small density

Stampable sheets available (Mo content not more than 75wt%)

Semi-finished or finished (Ni/Au plated) parts available
