Tungsten heavy alloy is increasingly adopted in tungsten alloy defense
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
they are in direct competition with depleted uranium (DU).

A significant mass of tungsten has been used to produce 5.56
mm ammunition for use at military training facilities as a substitute
for lead bullets. The mass of tungsten used in fixed target/fixed
firing position ranges has produced soils that are expected to contain
tungsten in the percent by mass concentrations, in addition to legacy
lead from past training.
Properties of tungsten heavy alloy
Tungsten heavy alloy have very high melting point and have a
density twice that of steel and are more than 50% heavier than lead.
Due to their high density, tungsten alloys offer greater radiation
shielding than lead and are non-toxic. Tungsten alloys are electrically
and thermal conductive and offer good corrosion resistance. They also
have a low coefficient of expansion and have a high modulus of
elasticity. Because of these unique properties tungsten alloys are used
extensively in military applications, balance weights, rocket
components, bullets, etc. The heavy-metal alloys are especially useful
for aircraft counterbalances and as weights in gyratory compasses.
Heavy-metal inserts are used as the cores of high-mass military
projectiles. Tungsten alloys are widely used for military defense.
