WNiFe ( Tungsten-Nickel-Iron Alloy Ring )
Tungsten alloy preformed fragment rings are pre-machined annular fragments manufactured from high-density tungsten alloy materials (typically W-Ni-Fe systems). Composed mainly of tungsten (W), nickel (Ni), and iron (Fe) via powder metallurgy, common formulations include 93%-95% W-Ni-Fe alloys. It can be designed as cylindrical, spherical, or other shapes to meet tactical requirements.

Tungsten Alloy Fragment Cylinders
| Annular preformed fragments, primarily used to enhance area or directional lethality in ammunitions such as missile warheads and landmines. Their ring structure enables uniform radial fragmentation for 360° lethal coverage. | Spherical preformed fragments, commonly applied in anti-aircraft grenades and air defense munitions. The aerodynamic symmetry of spheres ensures consistent velocity and uniform dispersion, optimizing hit probability over wide areas. | Block-shaped preformed fragments, configurable as cubes or polyhedrons based on tactical needs. Ideal for high-intensity penetration scenarios, their geometric design maximizes kinetic energy transfer against reinforced targets. | Cylindrical preformed fragments, combining high density with directional fragmentation characteristics. Frequently integrated into armor-piercing or HEAT (high-explosive anti-tank) projectiles to strengthen lethal mechanisms through controlled fragment trajectories. |
The Advantages of Tungsten Nickel Iron Alloy
I. High Density and High Kinetic Energy
With a density of 16-18.5g/cm³ (e.g., W221 model at 18.5g/cm³), significantly higher than steel (7.8g/cm³), they retain high kinetic energy upon explosion, enabling effective target penetration.
II. High Strength and Impact Resistance
Tensile strength ≥900MPa (e.g., W221≥920MPa), hardness HRC 27-40. They maintain integrity under explosive shock without easy fragmentation.
III. High Temperature and Corrosion Resistance
Capable of withstanding high-temperature environments and exhibiting excellent chemical stability, suitable for complex battlefield conditions.
IV. Design Flexibility
Customizable in shape, size, and distribution to adapt to kill requirements of different ammunitions, such as directional mines and missile warheads.
