Cu-Mo-Cu heat sink

Cu/Mo/Cu (CMC) is a sandwich composite including a molybdenum core layer and two copper clad layers. It has tailorable CTE, high thermal conductivity and high strength. All types of Cu/Mo/Cu sheets can be stamped into components.

The features of copper molybdenum copper

• Large sized sheets available (length up to 400mm, width up to 200mm)
• Can be stamped into components
• Very strong interface bonding which can repeatedly resist 850°C heat shock
• Tailorable CTE matching that of semiconductor and ceramic materials
• High thermal conductivity
• No magnetism
