Molybdenum Copper (Mo-Cu)
Our molybdenum copper products are manufactured by using a molybdenum skeleton and infiltrating with copper, a wrought powder metallurgy technology (PM). Molybdenum-copper is a composite material. It has similar thermal properties to the tungsten-copper composite, but its lower density makes it more suitable for applications where weight limitations are a factor.
HEXON offers and supplies tailored CTE of molybdenum copper and Cu:Mo:Cu laminates products according to customer’s specific demand and application. Typical technical properties of our molybdenum copper are given as below. If you have other special composite, please inform more details for our engineers to provide innovative solutions to your requirements.
