Molybdenum Copper Alloy

MoCu alloy is a kind of pseudo-alloy that is composed of Molybdenum and Copper. It consists of Molybdenum and Copper's characteristics, having high thermal conductivity, low thermal expansion coefficient, non-magnetic, low gas content, ideal vacuum performance, good machinability, special high-temperature performance.

Compared with WCu alloy, MoCu alloy has a lower density and is easier to stamp. It makes MoCu suitable for volume production.

Cu/Mo/Cu (CMC)

Description of CMC

Cu/Mo/Cu (CMC) is a sandwich composite including a Molybdenum core layer and two copper-clad layers. It has adjustable CTE and high thermal conductivity, making it suitable for the heat sink, head frame, and microchannel cooler for PCB. All types of CMC sheets can be stamped into components.

Cu/MoCu/Cu

Description of Cu/MoCu/Cu

Cu/MoCu/Cu is a sandwich composite similar to Cu/Mo/Cu, including a MoCu alloy core layer and two Copper clad layers. The normal proportion of MoCu alloy is Mo70Cu30, sometimes Mo50Cu50, and so on. The ratio of the CTE of Cu/MoCu/Cu is adjustable. It has different CTE in x, and y-direction, with higher thermal conductivity than WCu, MoCu & CMC. All types of Cu/Mo70Cu/Cu sheets can be stamped into components.

S-CMC

S-CMC is a sandwich composite with 5 or 7 layers with better thermal conductivity and anti-distortion ability than CMC. S-CMC is also suitable for stamping.
