Molybdenum Copper Alloy

Molybdenum Copper Alloy


Molybdenum copper alloy is a composite material of molybdenum and copper which has adjustable thermal expansion coefficient and thermal conductivity. But the density of molybdenum copper is much smaller than tungsten copper. Therefore, molybdenum copper alloy is more suitable for aerospace and other fields. Molybdenum copper product is more ablative, more plastic and workable than pure molybdenum product, so the molybdenum copper alloy can be used as high-temperature parts for the rockets and missiles in lower temperature, and it can also replace the molybdenum as the components in the other weapons.


1. This molybdenum copper product features high thermal conductivity and excellent hermeticity.
2. Molybdenum copper alloy is 40% lighter than comparable tungsten copper composite.


Our molybdenum copper alloy products, like molybdenum copper heat sinks, are widely used in applications such as microwave carriers, ceramic substrate carriers, laser diode mounts, optical packages, power packages, butterfly packages and crystal carriers for solid state lasers, etc.
