Product Brief Introduction:
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 XXmm, width up to XXXmm)
□ Can be stamped into components
□ Strong interface bonding resist to 850℃ heat shock repeatedly
□ Tailorable CTE matching that of semiconductor and ceramics
□ High thermal conductivity
