Application areas

Our 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.
