Tungsten Heavy Alloys Army Applications

Tungsten heavy alloys 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 heavy 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 heavy alloys are used extensively in military applications. The Army uses of powder metallurgy extend from the conventional press and sinter to the more exotic processes of liquid phase sintering of tungsten heavy alloys and powder injection molding. The Navy has taken great advantage of tungsten heavy alloys by employing them in the phalanx close-in weapon system. The Army intends that research will lead to an alloy or composite of tungsten, when used as a long rod penetrator, will perform as well as, or better than, current depleted uranium penetrators. Tungsten heavy alloys are the best choice when designers in defense industries. Tungsten heavy alloys are the ideal material which combines high density, good mechanical strength and which is easily machined, tungsten alloy for military defense is very important.
