WNiFe Tungsten Heavy Alloy Tungsten Nickle Iron Alloy For Aircraft / Vehicles The majority of current uses for tungsten heavy alloys are best satisfied with the W-Ni-Fe system. Tungsten alloys such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe tungsten alloy is a common approach for slight enhancement of both strength and ductility.
