Copper molybdenum sheet is a composite made from molybdenum and copper. Similar to copper tungsten alloy, CTE of copper molybdenum sheet can also be tailored by adjusting the composition. But copper molybdenum sheet is much lighter than copper molybdenum sheet, so that it is more suitable for aeronautic and astronautic applications.
The advantages of copper molybdenum alloy
- High thermal conductivity due to no sintering additives were used
- Excellent hermetic
- Relatively small density
- Stampable sheets available
- Semi-finished or finished (Ni/Au plated) parts available
