Features And application of Tungsten Heavy Alloy WNiFe Rod
High Density: The density of WNiFe alloy rods is extremely high, typically ranging between 17.0-18.8 g/cm³, making them excel in applications requiring substantial weight and stability.
High Strength and Toughness: This alloy boasts exceptional tensile strength and toughness, enabling it to withstand high stress and strain. For example, the tensile strength of 97% WNiFe alloy can reach up to 840 MPa.
Good Ductility: Despite its high density, WNiFe alloy retains a certain level of ductility, facilitating processing and shaping. For instance, the elongation rate of 90% WNiFe alloy can reach 10%.
High-Temperature Resistance: Tungsten has an extremely high melting point (over 3420°C), and the alloy maintains excellent high-temperature performance, making it suitable for aerospace and other high-temperature environments.
Radiation Resistance: In radioactive environments, WNiFe alloy exhibits outstanding radiation resistance, making it ideal for use in shielding against radioactive materials.
Applications
Military and Defense: WNiFe alloy rods are commonly used to manufacture armor-piercing projectile cores, medium- and large-caliber ammunition cores, and prefabricated fragments for pre-fragmented munitions. Their high density and strength enable effective armor penetration.
Aerospace: In the aerospace sector, WNiFe alloy is employed to produce helicopter rotor blades, aircraft control surfaces, and other components. Its high density contributes to better balance and counterweight.
Industrial Applications: WNiFe alloy rods are also used to manufacture high-precision counterweights, radiation shielding materials, and high-temperature tools.
Medical Field: Due to its high density and excellent radiation shielding properties, WNiFe alloy can be used to produce shielding materials for radioactive isotopes, such as cobalt-60.

What is WNiFe alloy?
WNiFe (Tungsten-Nickel-Iron) is a high-density alloy composed primarily of tungsten (W), with nickel (Ni) and iron (Fe) as binding materials. It offers exceptional density, strength, and radiation shielding properties.
How does WNiFe compare to pure tungsten?
While pure tungsten has a higher melting point and density, WNiFe is easier to machine due to its ductility. The alloy also offers better impact resistance and structural stability.
Can WNiFe alloy be machined or welded?
Yes, WNiFe is more machinable than pure tungsten but still requires specialized tools due to its hardness. Welding is possible but challenging-consult manufacturers for best practices.
Is WNiFe alloy corrosion-resistant?
It has moderate corrosion resistance but may require protective coatings in harsh environments (e.g., marine or chemical exposure).
What are the standard sizes and compositions available?
Common compositions include 90% W, 7% Ni, 3% Fe and 97% W, 2% Ni, 1% Fe. Rod diameters and lengths vary based on application-custom sizes are often available.
Is WNiFe toxic or hazardous?
Tungsten itself is biocompatible, but nickel content may cause allergies in some individuals. Proper handling (e.g., gloves, ventilation) is recommended during machining.
