90WNiFe Tungsten Alloy Radiation Shielding Parts

1. What Are 90WNiFe Tungsten Alloy Radiation Shielding Parts?
90WNiFe tungsten alloy radiation shielding parts are high-density radiation shielding components manufactured through powder metallurgy, with tungsten as the matrix and nickel and iron as binder phases. High atomic number (Z=74) and high density enable effective absorption and attenuation of X-rays and γ-rays through mechanisms including the photoelectric effect and Compton scattering, providing localized radiation shielding in radiotherapy, nuclear medicine, industrial inspection, and related equipment.

2. Features of CTIA’s 90WNiFe Tungsten Alloy Radiation Shielding Parts
(1) Effective Radiation Shielding: Density of approximately 17.1 g/cm³ enables effective attenuation of X-rays and γ-rays, providing high shielding efficiency within limited space.
(2) High Strength and Impact Resistance: Tensile strength of approximately 750–950 MPa and elongation of approximately 10%–18% provide good load-bearing and impact resistance.
(3) Good Dimensional Stability: Coefficient of thermal expansion of approximately 4.5–5.5×10⁻⁶/℃ minimizes dimensional variation under temperature fluctuations, ensuring consistent fit for precision shielding structures.
(4) Non-Toxic and Eco-Friendly: Lead-free composition eliminates lead pollution and subsequent disposal issues.
(5) Good Precision Machinability: Supports precision turning, milling, drilling, and grinding, meeting manufacturing requirements for channels, slots, curved surfaces, and customized geometries.
(6) Flexible Structural Forms: Can be processed into shielding plates, blocks, tubes, rings, collimator leaves, and customized parts to fit diverse equipment structures.
