W-Ni-Fe Tungsten Alloy Radiation Shielding Parts

1. What Are W-Ni-Fe Tungsten Alloy Radiation Shielding Parts?
W-Ni-Fe 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 iron as binder phases. CTIA’s W-Ni-Fe tungsten alloy radiation shield combines excellent radiation shielding capability with strong overall mechanical properties, making it suitable for medical, nuclear, industrial inspection, and scientific research applications.

2. Features of CTIA’s W-Ni-Fe Tungsten Alloy Radiation Shielding Parts
(1) Effective Radiation Shielding: Density of approximately 16.7–18.8 g/cm³ provides effective X-ray and γ-ray attenuation, enabling smaller structures under equivalent shielding performance.
(2) High Structural Strength: Tensile strength typically reaches 900–1200 MPa, combining radiation shielding with structural load-bearing capability and reducing the combined use of separate steel structures and lead shielding layers.
(3) Thermal Stability: Thermal expansion coefficient of approximately 4–6 × 10⁻⁶/K provides good dimensional stability under temperature variations, supporting precision equipment and long-term operation.
(4) Precision Machining: Turning, milling, grinding, and wire EDM are supported, with tolerances down to ±0.02 mm.
(5) Lead-Free and Environmentally Friendly: Free of toxic heavy metals such as lead, reducing pollution issues associated with conventional lead shielding materials during production, use, and disposal.

3. Types of CTIA’s W-Ni-Fe Tungsten Alloy Radiation Shielding Parts
(1) Shielding Plates: For equipment panels and localized radiation protection.
(2) Shielding Tubes and Rings: For shielding around pipelines, detectors, and radioactive sources.
(3) Shielding Blocks: For localized shielding, modular shielding, and structural filling.
(4) Shielding Covers: For protecting radioactive sources, radiation components, and equipment parts.
(5) Shielding Containers: For storage, transport, and handling protection of radioactive isotopes and radiopharmaceuticals.
(6) Collimation Structures: For radiation beam shaping, collimation, and directional control.

4. Applications of CTIA’s W-Ni-Fe Tungsten Alloy Radiation Shielding Parts
(1) Medical: Used in collimators, shielding blocks, shielding covers, and radiopharmaceutical containers for Computed Tomography (CT), Positron Emission Tomography (PET), gamma cameras, and nuclear medicine equipment, as well as collimation components in radiotherapy equipment.
(2) Nuclear Industry: Used for nuclear facility shielding structures, radioactive waste containers, nuclear fuel transport shielding components, and nuclear measurement equipment.
(3) Industrial Non-Destructive Testing: Used for shielding housings and localized protection components in industrial CT, X-ray inspection, and γ-ray inspection equipment.
(4) Aerospace: Used for radiation protection of spacecraft electronics, satellite payloads, and aerospace electronic systems.
(5) Scientific Research: Used for shielding structures in high-energy physics experiments, radiation experimental equipment, and research laboratories.
(6) Oil Well Logging: Used for localized shielding of radioactive sources such as Cs-137 and detector protection in oil and gas exploration logging instruments.
(7) Security Screening Equipment: Used for localized radiation shielding of X-ray generators and detector components.
