Tungsten alloy fragment is a kind of components used in land mines and grenades that can form a large number of high-speed fragments under the action of high-energy explosives and use the high-speed impact of the fragments to ignite and detonate the target, thereby killing the enemy's vital forces, (people, animals), unarmored or light armored vehicles, aircraft, radar, missiles and other weapons or equipment.

The reason why tungsten alloy fragment can effectively kill the target is related to its own raw material - tungsten alloy, and is also closely related to the shape of the fragment and the speed when the fragment hits the target.
There are three types of tungsten alloy fragments according to the generation method of fragments. They are tungsten alloy natural fragments, tungsten alloy pre-controlled fragments and tungsten alloy prefabricated fragments. It forms a three-dimensional killing area in the space. The shape and size of the three-dimensional killing area are determined by the fragmentation characteristics of the fragments including fragment scattering angle and directional angle, as well as the variance of the distribution density of fragment number along the directional angle.
