At temperatures between 1000 and 1600°C the semi-finished products receive their basic shape by forging, round hammering, rolling or extrusion. Work pieces with very low tolerances can be produced by a subsequent surface grinding operation.

Since the melting point of tungsten has reached 3380°C, rolled tungsten sheets are widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, sputtering target applied in plasma coating film, and high temperature resistance boat. Tungsten sheets and disk are available with alkali washed or ground finish.

Tungsten sheets applications
After rolling and processing with deflection reaching 60% , the density of tungsten sheet basically comes close to tungsten’s theory density. Therefore, tungsten sheet possesses the properties of high shield, heating tape, connecting pieces applied in vacuum furnace, titanium sputtering target applied in plasma coating film, and high temperature resistance boats.
