99.95% Pure Tungsten Products for Sapphire Industry Tungsten Square Bars
Because of super high melting point 3400°C of pure tungsten material, tungsten squre base are widely used in steel making industry and sapphire industry. The bars 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 square bars
The purity of the tungsten square bar is higher than 99.95%. The density of the tungsten bars is 19.3g/cm3. The size of the tungsten bars is T0.05-50mmxW50-500mmxL100-1000mm. The surface of the tungsten square bars is chemical cleaned or the polished. The tungsten square bars meet the standard ASTM B760/GB T3875.
Application of tungsten square bars
The tungsten square bars are widely used in electronics, illumination, vacuum plating, electron-vacuum, shield and the high temperature furnace industry.
