One prior approach to inducing tungsten alloy fragmentation control to an integral warhead and missile structure has been to include grooves on either the external or internal wall surfaces of the structure to delineate fragments or projectiles in a combined warhead and missile structure. Explosives are installed in proximity to the grooves. When the explosives are detonated, the grooves create stress concentrations that cause the structure to fracture along the grooves, forming tungsten fragments.
Still another approach is the dual-wall naturally fragmenting (and combination natural fragmenting and scored wall) warhead. While these types of warheads have provided somewhat of an improvement over single-wall naturally fragmenting warheads, current dual-wall designs generally require thermal conditioning manufacturing methods to mate walls together with tight circumferential tolerances. We can provide different size tungsten alloy fragment according to your requirement, tungsten fragment is one of our leading products.
