93 Tungsten Nickel Iron Spheres

93 tungsten nickel iron spheres are high-density metal spheres made from a tungsten heavy alloy (W-Ni-Fe) with 93% tungsten content. This alloy combines the exceptional density, strength, and wear resistance of tungsten with the improved machinability and toughness provided by nickel and iron binders. These spheres are widely used in industries requiring high-density materials for precision counterweights, kinetic energy applications, and radiation shielding.
