92.5WNiFe Tungsten Alloy Rod

1. What's 92.5WNiFe Tungsten Alloy Rod?
92.5WNiFe tungsten alloy rod is tungsten heavy alloy rod based on 92.5% tungsten (W), with nickel (Ni) and iron (Fe) added as binder phases, providing high density, high strength, and good plasticity. CTIA’s tungsten alloy rod is manufactured through powder metallurgy processes, including powder mixing, pressing, liquid phase sintering, and precision machining. It features high density, high strength, high hardness, good machinability, and excellent radiation shielding capability, and is widely used in aerospace counterweights, medical protection, precision instruments, and high-end equipment.
2. Chemical Composition of CTIA’s 92.5WNiFe Tungsten Alloy Rod
92.5WNiFe tungsten alloy rod is a W-Ni-Fe series high specific gravity tungsten alloy. By adjusting the ratio between tungsten phase and binder phase, the material achieves a balance between high mass density and good mechanical properties. Its typical chemical composition includes:
(1) Tungsten (W): 92.5%
(2) Nickel (Ni): 5.0%–6.0%
(3) Iron (Fe): 1.5%–2.5%
The tungsten phase provides high density, high strength, and radiation absorption capability, while the nickel-iron binder phase improves toughness and machinability.
3. Physical Performance of CTIA’s 92.5WNiFe Tungsten Alloy Rod
92.5WNiFe tungsten alloy rod features a stable microstructure and excellent overall performance. The main physical parameters are as follows:
(1) Density: 17.5–18.5 g/cm³
High-density characteristic enables large mass configuration within limited space.
(2) Tensile Strength: approximately 700–900 MPa
