Tungsten Heavy Alloys are tungsten alloys that typically contain 90 to 98 wt% W. Most commercial tungsten alloys are two-phase structures, the principal phase being nearly pure tungsten in association with a binder phase containing the transition metals plus dissolved tungsten. As a consequence, Tungsten Heavy Alloys derives their fundamental properties from those of the principal tungsten phase, which provides for both high density and high elastic stiffness. It is these two properties that give rise to must applications for this family of materials.
The majority of current uses for Tungsten Heavy Alloys are best satisfied with the W-Ni-Fe system. such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe is a common approach for slight enhancement of both strength and ductility. The presence of cobalt provides solid-solution strengthening of the binder and slightly enhanced tungsten-matrix interfacial strength. Cobalt additions of 5 to 15% of the nominal binder weight fraction arc most common.
The current uses of tungsten heavy alloy are spanning a wide range of consumer, industrial, and government applications that include:
Balancing weights for ailerons in commercial aircraft, helicopter rotors, and for guided missiles.
Kinetic energy for defeating heavy armor
Fragmentation warheads
Radiation shielding, radio isotope containers and collimation apertures for cancer therapy devices
High performance lead-free shot for waterfowl hunting.
Many applications that require high density for balance weights, inertial masses, or kinetic energy or high density for radiation shielding and necessitate rather large bulk shapes. Such a requirement eliminates all but a few candidates on the basis of prohibitive cost, typically reducing the choice of very dense alloys down to either tungsten- or uranium-base materials.
