New product
Cu/MoCu/Cu is a flat-panel composite material with a sandwich structure, consisting of a molybdenum-copper alloy core layer and two copper-clad layers. The typical composition of the MoCu alloy is Mo70Cu30, although Mo50Cu50 and other variations are also used. The coefficient of thermal expansion (CTE) of Cu/MoCu/Cu can be adjusted according to specific requirements.

Cu/MoCu/Cu (CPC) is a sandwich composite similar to Cu/Mo/Cu, consisting of a Mo-Cu alloy core layer and two copper-clad layers. The thickness ratio of Cu:Mo-Cu:Cu can be adjusted accordingly. With superior thermal conductivity compared to W(Mo)-Cu and Cu/Mo/Cu, CPC offers a cost-effective solution with a higher price-to-quality ratio.
