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.
Features:
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℃ heat shock.
Tailorable CTE matching that of semiconductor and ceramic materials.
High thermal conductivity.
No magnetism.
