Product Brief Introduction:
Cu/Mo70Cu/Cu(CPC) is a sandwich composite similar to that of Cu/Mo/Cu including a Mo70-Cu alloy core layer and two copper clad layers. The ratio of the thickness in Cu: Mo-Cu: Cu is 1:4:1. It has different CTE in X and γ direction, with higher thermal conductivity than that of W (Mo)-Cu & Cu/Mo/Cu and less expensive. All types of Cu/Mo70Cu/Cu sheets can be stamped into components,.

Features of Cu/Mo70Cu/Cu
□ Large sized sheets available (length up to XXmm, width up to XXmm)
□ More easily to be stamped into components than CMC
□ Very strong interface bonding which can repeatedly resist 850℃ heat shock
□ Higher thermal conductivity and lower cost
