Molybdenum Copper
Molybdenum copper is alloy of molybdenum and copper. It is a great alternative to tungsten copper for weight sensitive applications. The combination of high purity raw materials and high temperature hydrogen sintering using no additives yields the highest thermal conductivity available for this composite material system.
Molybdenum copper composite materials are produced by copper infiltration of sintered molybdenum. They are available with different copper contents (15-35%).
