rWNiCo: tungsten (91–93%), nickel (3–5%) and cobalt (2–4%) rWNiFe: tungsten (91–93%), nickel (3–5%) and iron (2–4%) Upon detonation of the explosive, the casing disintegrates into extremely small particles, as opposed to larger pieces of shrapnel which results from the fragmentation of a metal shell casing. The HMTA powder acts like ...
