Tungsten-Copper high performance composites are fabricated from carefully controlled porous tungsten that is vacuum infiltrated with molten copper. This results in a W/Cu composite that has high conductivity and a matched low thermal expansion for heat sinks.
It is a composite of tungsten and copper. By controlling the content of tungsten, we can design its coefficient of thermal expansion (CTE), matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Kovar, etc.
Advantages: High thermal conductivity, Excellent hermeticity, Excellent size control, surface finish and flatness, Semi-finished or finished (Ni/Au plated) products available
properties of WCu and MoCu heat materials
Molybdenum-Copper for Heat Sinks
Molybdenum Copper heat sink 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
