Tungsten, also known as wolfram which is a chemical element with the symbol of W. Tungsten Metal is a hard, rare metal, 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. We can supply many kinds of tungten products, like tungsten sheet, tungsten tube, tungsten bar, tungsten foil, tungten crucibe, tungsten boat, tungsten heating elements and other tungsten deep processing parts. The tungsten products are 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 and so on.
