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;
Relatively small density
Stampable sheets available (Mo content not more than 75wt%)
Semi-finished or finished (Ni/Au plated) parts available
properties of WCu and MoCu heat materials
