W-Ni-Cu Tungsten Alloy Radiation Shielding Parts

1. What Are W-Ni-Cu Tungsten Alloy Radiation Shielding Parts?
W-Ni-Cu tungsten alloy radiation shielding parts are high-density shielding components manufactured through powder metallurgy and precision machining, with tungsten as the matrix and nickel and copper as binder phases. High atomic number (Z=74) and density provide effective X-ray and γ-ray attenuation. Compared with W-Ni-Fe alloy, W-Ni-Cu alloy offers non-magnetic performance, corrosion resistance, and good machinability, with relative magnetic permeability close to 1, making it suitable for Magnetic Resonance Imaging (MRI) and other magnetically sensitive equipment.

2. Features of CTIA’s W-Ni-Cu Tungsten Alloy Radiation Shielding Parts
(1) Effective Radiation Shielding: Density of 17.0–18.0 g/cm³ provides excellent X-ray and γ-ray attenuation, enabling smaller structures and thinner shielding walls under equivalent protection levels.
(2) Completely Non-Magnetic: Relative magnetic permeability close to 1 produces virtually no ferromagnetic interference, making the material suitable for MRI, precision sensors, and other strong magnetic field or electromagnetically sensitive environments.
(3) Good Corrosion Resistance: The copper phase helps improve corrosion resistance, supporting use in humid environments, frequent disinfection, and mildly corrosive conditions while maintaining long-term dimensional stability.
(4) Good Machinability: Turning, milling, grinding, and other precision machining processes are supported, making complex shielding structures and precision assembly possible.
(5) Lead-Free and Environmentally Friendly: Free of lead and radioactive materials, reducing contamination risks associated with conventional lead shielding materials.
