Application: Owing to its high density and hardness, resistant to high temperature, thermal conductivity, the tungsten ball is widely used in aviation, military, metallurgy, building materials. It’s mainly made into rocket motor throat liner, X ray generator target, armor warhead, rare earth electrode, glass furnace electrode and so on. 1.Tungsten ball could be manufactured as the parts of military defense and extrusion die; 2. In semi-conductor industry, tungsten parts are mainly used in ion implantation equipment. The tungsten alloy ball is small in volume and high in specific gravity, and can be used in the fields that require small parts with high specific gravity, such as golf weights, fishing sinkers, weights, missile warheads, armor-piercing bullets, shotgun bullets, prefabricated fragments, oil drilling platforms . Tungsten alloy balls can also be used in high-precision fields, such as mobile phone vibrators, balance of pendulum clocks and automatic watches, anti-vibration tool holders, flywheel weights, etc. High specific gravity tungsten alloy balls are widely used in industrial and military fields as balance weights. | Size ( mm ) | Weight ( g ) | Size Tolerance ( mm ) | Weight Tolerance ( g ) |
