After rolling and processing with deflection reaching 60% , the density of molybdenum sheet basically comes close to molybdenum’s theory density. Therefore, molybdenum sheet possesses the properties of high density, balanced internal structure and excellent high creep strength temperature. Molybdenum sheet is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, titanium sputtering target applied in plasma coating film, and high temperature resistance boats.
