What is high-density tungsten heavy alloy (WNIFE)?

High-density tungsten heavy alloy (WNIFE) is a composite material primarily composed of tungsten (W), nickel (Ni), and iron (Fe). It offers an exceptional combination of high density (17.0–18.75 g/cm³), strength, machinability, and radiation shielding, making it ideal for demanding industrial and defense applications.

What are the key properties of tungsten heavy alloy?

Extremely high density (near 18 g/cm³, 50% denser than lead)

High tensile strength (700–1000 MPa) and toughness

Excellent machinability (can be precision-machined into complex shapes)

Superior radiation shielding (30–40% better than lead)

High melting point (~3400°C) and thermal stability

Good corrosion & oxidation resistance

Can tungsten alloy be machined into complex shapes?

Yes! Unlike pure tungsten (which is brittle), WNIFE alloys are highly machinable and can be turned, milled, drilled, or EDM-processed into precision components like molds, balancing weights, and shielding parts.

Is tungsten alloy corrosion-resistant?

Yes, it offers good corrosion and oxidation resistance, making it suitable for harsh environments, including marine and chemical applications.

Why is tungsten alloy used in aerospace balancing?
