99.95% Purity Tungsten Products, Tungsten Metal Wolfram Plates for Vacuum Furnace / Sapphire Growth
Because the melting point of tungsten has reached 3380°C, the tungsten plates are widely used in reflection shield. The cover plates 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 plates
The purity of the tungsten plats 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 plates are widely used in electronics, illumination, vacuum plating, electron-vacuum, shield and the high temperature furnace industry.
