After rolling and processing, the density of tungsten sheet with deflection reaching 60% basically comes close to tungsten's theory density. Therefore, tungsten sheet possesses the properties of high density, balanced dnternal stracture and excellent high creep strength temperature. Tungsten 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 resustance boats.
