Copper Molybdenum Copper Alloy

Description

Copper molybdenum copper alloy, also known as CMC alloy, is a sandwich structured and flat-panel composite material. It uses pure molybdenum as the core material, and is covered with pure copper or dispersion strengthened copper on both sides.
Besides, copper molybdenum copper alloy has adjustable coefficient of thermal expansion, high thermal conductivity, and high thermal stability. The production process of it commonly uses method of rolling composite, plated composite and explosive forming. It has very strong interface bonding that can resist 850°C heat shock repeatedly and features no magnetism.

Application

Copper molybdenum copper alloy is mainly used as the bottom expansion and thermal conductivity channel of the heat sink, the lead frame and the multilayer printed circuit board (PCB).
