Nowadays, tungsten heavy alloy is increasingly adopted as the raw material to make parts of military products, such as bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads, bulletproof vehicles, tank panzers, cannons, firearms, etc. A major use for tungsten heavy alloy is in kinetic energy penetrators, where is in direct competition with depleted uranium. Recent investigation shows that depleted uranium's superior properties resulted from its ability to localize shear during ballistic penetration events. Therefore, it was argued that if localized shear will be imparted to tungsten heavy alloys, these alloys would exhibit penetration performance matching that of depleted uranium (which had become an environmental problem).

In fact, in the World War Ⅱ, tungsten has already been used as an important raw material to make weapons for military defense. There is abundant wolframite ore reserves found then in Portugl, which is used to produce tungsten concentrates. In order to reduce the adoption of environmental hazardous materials in the military field, tungsten related products are used as a nontoxic substitute for lead and depleted uranium in bullet and shot. High-density metals such as tungsten are now widely employed; the goal is to create functional, high density, non-toxic arms projectiles with controlled impact behavior.
