Tungsten-nickel-iron alloys are alloys based on tungsten (about 90~98%) with the addition of nickel, iron, copper or other group elements, and the specific gravity is generally 17.0~18.5. Proportioning tungsten-nickel-iron alloys are a kind of important tungsten-based heavy alloys. They are alloys formed by adding nickel and iron to tungsten, as well as alloys to which other metal elements are added on this basis. The ratio of nickel to iron added is generally 7:3 or 1:1.

Tungsten-nickel-iron alloy is characterised by high sintered density, good strength and plasticity, and ferromagnetism. It has good plasticity and machinability, good thermal and electrical conductivity, and good absorption of γ-rays or X-rays. Specific gravity: general specific gravity of 16.5-18.75g/cm3; high strength: tensile strength of 700-1000Mpa; high ray absorption capacity: 30-40% higher than lead.
