Tungsten alloy controlled fragment is made of pre-processed tungsten alloy fragments, which is glued to the outer lining of the charge or the inner cavity of the warhead shell to maintain a certain shape. It is mainly used for high energy explosive. The commonly used controlled fragments are spherical, cube, rod, short column and arrow.
Controlled fragments of different shapes have different effects on the damage effect of fragments. The best match between the mass, shape and speed of the fragment can be achieved in the design ammunition, thus the prefabricated fragment has been widely used. For any given target, the optimum killing effect can be achieved by designing suitable prefabricated chip shapes and materials.
