Tungsten Prefabricated Fragments

Fragmentation Damage Warhead's Mechanism and Characteristic

Fragmentation warhead is one of the main types of warheads, mainly by the role of high-energy explosives, the formation of a large number of high-speed fragments, using high-speed hitting the tungsten prefabricated fragments, the role of ignition and detonation damage targets, and can be used for anti-effectives (human, animal), no armor or light armored vehicles, aircraft, radar and missiles and other weapons and equipment. According to the generation of fragments channels, fragmentation warhead can be divided into natural, pre-control and pre-fragmented warhead three types.

Tungsten prefabricated fragments are natural under detonation. Tungsten alloy ball, the shell expansion, fracture broken of such warheads is characterized not only as a container shell to form another anti-elements, fragments the size of the uneven, irregular shape in the air fast decay in flight speed, so that the effective anti-personnel grenade is limited in scope. Usually, tungsten prefabricated fragments made from tungsten alloy ball. We can provide different sizes of tungsten alloy balls in accordance with your requirements.

Pre-control use of shell fragments groove, groove or increase the lining of explosives and other technical measures to make the shell partial reduction of the intensity to control the explosion of the broken parts to form fragments. Such warheads are characterized by the formation of uniform fragment size and shape. Tungsten alloy ball is one among our leading products.

Tungsten prefabricated fragments forming pre-processing will be the shape and quality of pre-designed tungsten alloy ball, steel arrows, tungsten alloy ball, tungsten alloy ball and other prefabricated column fragments produced prefabricated sets of body fragments and installed in the grenade projectile outer surface or inner surface. Tungsten alloy ball prefabricated projectile fragmentation grenade explosion with the formation of fragments together constitute the natural fragmentation field, due to resistance of tungsten prefabricated fragments flying characteristic consistency, with tungsten prefabricated fragments of the grenade will be set within the framework of the lethal effect of a relatively dense, full-bombs a greater degree of lethality increase.

Because there is a tungsten prefabricated fragments will affect the negative effects of missile body structures, usually only in low-pressure chamber which uses artillery and ammunition, such as the forced large-caliber bullets and grenades. Applications also are the most common aircraft shells, grenades, mines and so on. The current high chamber pressure prefabricated artillery fragments, are used in canister form, such as Switzerland, L70-type 40 mm grenade where overhead is filled with tungsten alloy ball. Tungsten prefabricated fragments technology has been widely used on all types of warheads. Cylindrical fragments (Tungsten column) as a type of tungsten prefabricated fragments, due to high density, armor-piercing capability, as air defense, anti-radiation, anti-surface, one of the main anti-elements, and widely used.
