Cu/Mo70Cu/Cu (CPC) is a sandwich composite like 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 Y direction, higher thermal conductivity than that of W(Mo)-Cu、Cu/Mo/Cu and more cheap. All types of Cu/Mo70Cu/Cu sheets can be stamped into components.

Features:
Large sized sheets available (length up to 400mm, width up to 200mm)
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
No magnetism
