Molybdenum-copper (MoCu15) is a composite material which contains 15 percent copper by weight. This composite combines the high thermal conductivity of copper and the low thermal expansion of molybdenum.
MoCu is perfect for the manufacture of passive cooling elements (heat sinks and heat spreaders) in electronic components. Due to their low weight, molybdenum-copper composites are particularly suitable for this type of application where every gram counts: In the automotive industry they are used as carrier plates for the IGBT modules that act as inverters in electric drives.
