Tungsten alloy controlled fragment, or tungsten alloy prefabricated fragment, can be tungsten alloy cylindrical fragment (tungsten pillars) or tungsten alloy spherical fragment (tungsten balls), ranging in size from 2mm to 100mm. They are used in mines, grenades and other ammunitions, to effectively kill the enemy's vital forces.

Tungsten alloy controlled fragment has the characteristics of high density (small size, large destructive force), high temperature resistance, good impact resistance, corrosion resistance, etc., and has been widely used in various types of warheads, becoming one of the main killing elements of air defense. Because tungsten alloy prefabricated fragment has a negative effect on the structure of the projectile, it is usually only used in low-bore pressure artillery ammunition, such as mortar shells and large-caliber grenades. The prefabricated fragments used in the high-pressure artillery are all in the form of grapeshots. For example, there are tungsten carbide balls in the Swiss L70 40mm anti-aircraft grenade.
