Highly polished tungsten alloy shot is a low toxic shot comprised of tungsten alloys (W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe) that are similar in density to lead. Highly polished tungsten alloy shot has better properties than lead shot as tungsten alloy has characteristics of small size, high hardness, high density (1.7 times higher than lead), high temperature resistance, corrosion resistance and wear resistance.

And therefore, tungsten alloy has been widely used in production of heads of missiles and armor-piercing projectiles, cores of bullets, prefabricated fragments, and so on. There is no doubt that tungsten alloy products are popular in national defense. In many countries and regions, lead bullets have been banned as they pollute the environment. It means that lead bullets are losing their market. In contrast, highly polished tungsten alloy shots are gradually gaining popularity in the world market.
