Quality Standard
GB/T 3875-2006 (Tungsten Plate)
As a high-performance material, pure tungsten has the advantages of high melting point, high density, low vapor pressure, low thermal expansion and good thermal conductivity, sufficient electrical resistance, and high elastic modulus.
Tungsten sheets and discs are available with an alkaline wash or a polished finish.
Pure tungsten products are widely used in furnace parts, semiconductor substrates, electron tube assemblies, electron beam evaporation emission cathodes, ion implantation cathodes and anodes, capacitor sintering tubes/boats, X-ray diagnostic targets, crucibles, heating elements, X-ray radiation shielding, sputtering Shooting targets, electrodes.
