Tungsten has the highest melting point among all melts. The prominent advantage of high melting point is it produces materials with good high temperature strength and corrosion-resistance, which shows its excellent properties in military industry, especially in tungsten alloy shot.
Tungsten alloy shot is used as the shot for shotgun hunting shells. The pellets spread upon leaving the barrel, and the power of the burning charge is divided among the pellets, which means that the energy of any one ball of shot is fairly low. Other main advantages of tungsten are that it's very dense, and very hard. The density allows the pellets to fly long distances without slowing down, while the hardness allows the pellets to keep their shape while being accelerated by the powder charge, which increases the muzzle velocity.
More than 90 million rounds of the tungsten alloy shot have been used in the United States, since World War Ⅱ. It relies on a blend of tungsten and nylon, or tungsten and tin. That gives the shot the same density and firing properties as the original, but without using lead. Tungsten alloys are dense heavy metal composite materials used primarily in military industry.
