99.95% Tungsten Metal Flat Elements Tungsten Plates For Sapphire Growth and Heating
Because the melting point of tungsten has reached 3380°C, the tungsten flat elements are widely used in reflection shield. The cover flats are applied in the sapphire growth furnace, reflection shield, heating tape and so on. The connecting pieces are applied in vacuum furnace.
The features of the tungsten flat elements
The purity of the tungsten elements is higher than 99.95%. The density of the tungsten plates is 19.3g/cm3. The size of the tungsten plates is T0.05-50mmxW50-500mmxL100-1000mm. The surface of the tungsten plates is chemical cleaned or the polished. The tungsten plates meet the standard ASTM B760/GB T3875.
Application of tungsten Plates
The tungsten flat plates are widely used in electronics, illumination, vacuum plating, electron-vacuum, shield and the high temperature furnace industry.
