After rolling with more than 60% deformation, the density of molybdenum sheet is basically close to the theoretical density of molybdenum, featuring high strength, uniform internal structure and excellent high-temperature creep resistant performance, so it is widely used in the reflection screen and cover plate in sapphire crystal growth furnace; the reflection screen, heating belt and connector in vacuum furnace; the sputtering target for plasma deposition; high-temperature resistant boat and other products.
