MSE PRO™ 3N5 (99.95%) Molybdenum (Mo) Pellets Evaporation Materials

The vast majority of molybdenum (Mo) is used in metallurgical applications. Mo-base alloys offer high stability, high creep resistance, high thermal conductivity and exceptional strength at high temperature, which make them suitable for refractory applications including fission and fusion reactors, rocket engine nozzles, missiles, turbines, furnace structural components, and forging dies. Molybdenum coatings have attracted much attention as the candidates of the sliding materials due to their excellent wear resistance properties, which has been ascribed to a lubricating transfer film formed on the wear tracks. It is also evaporated under vacuum to make advanced sensors, semiconductors and displays.

The dimensions and purities can be customized upon request. Please contact us for customization or bulk orders.
