Descrizione del prodotto

tungsten foil

Product Description
Production process of tungsten foil 
Materials---hot rolling---annealing---cold rolling---leveling---annealing---machining---tungsten sheet

Production equipments 
four-high cold mill, vacuum annealing furnace, W43G series straightener, hydraulic plate shears, water jet, wire cutting machine, flat-stone mill

Applications of Tungsten Foil
Since the melting point of tungsten has reached 3380oC, 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, sputtering target applied in plasma coating film, and high temperature resistance boat.
