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.

Quality standard 
GB/T 3875-2006 (tungsten plate)

As a high performance materials, pure tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance, high modulus of elasticity.
Tungsten sheets and disk are available with alkali washed or ground finish.  

Pure tungsten Products is widely used for Furnace parts, Semiconductor Base Plates, Components for Electron Tubes, Emission Cathodes for Electron Beam Evaporation, Cathodes and Anodes for Ion Implantation, Tubes / Boats for Sintering of Capacitors, Targets for X-ray Diagnostics, Crucibles, Heating Elements, X-ray Radiation Shielding, Sputtering Targets, Electrodes.
