Tungsten alloy spherical fragment mainly relies on the kinetic energy of fragment to destroy targets, and have gradually become the first choice of damage elements for air defense and other types of killing warheads. Although the spherical fragments only have the simplest geometry, they have excellent characteristics that the tungsten alloy material gives it - high density (small volume), high hardness, good wear resistance, strong armor piercing ability, strong lethality, and no major energy loss while maintaining speed.

Normally, the lethality of tungsten alloy spherical fragments is measured by the kinetic energy of the target or the ability to transmit in the target. Therefore, the process of fragmentation killing the target is a process of energy release and transmission. In other words, the degree of fragmentation damage to the target depends on how much energy is transferred. Within a certain diameter range, the smaller the fragment, the higher the efficiency of energy transfer.
