Tungsten Alloy Used for Weapon

Part of the problem is that so many types of weapon use tungsten:

• The GNU-44 Viper Strike missile, carried by armed drones, has a tungsten sleeve to produce antipersonnel shrapnel.

• The 130-round-per-second Phalanx anti-missile Gatling gun, deployed on U.S. and Royal Navy ships, originally used DU rounds. They were replaced with tungsten, for environmental reasons.

• 120mm anti-tank rounds, use tungsten as an alternative to DU in training. So do the 25mm anti-tank rounds, on board the M2/M3 Bradley fighting vehicle.

• Armor-pirecing .308 M993 rifle rounds.

• The 120mm M1028 anti-personnel round, fired by the Abrams tank. It's basically a giant shotgun shell loaded with 1100 tungsten balls, each 3/8th of an inch big.

• Dense Inert Metal Explosives, the "focused lethality" munition used by the U.S. and Israel. It contains micro-shrapnel made of tungsten powder.

• Some 70mm rockets fired by Apache helicopters release tungsten flechettes.
