High Density Tungsten Alloy Radiation Shielding Parts

1. What Are High Density Tungsten Alloy Radiation Shielding Parts?
High density tungsten alloy radiation shielding parts are radiation protection components made from tungsten heavy alloy, including W-Ni-Fe and W-Ni-Cu. CTIA’s high density tungsten alloy shielding parts utilize tungsten’s high atomic number (Z=74) and high density to effectively attenuate X-rays, γ-rays, and other ionizing radiation. CTIA's high density tungsten alloy radiation shielding parts combine high shielding efficiency, lead-free performance, high strength, and compact structures, and are manufactured into shielding blocks, plates, tubes, radioactive source containers, collimators, and other components for medical, nuclear medicine, industrial inspection, nuclear industry, and advanced equipment applications.

2. Features of CTIA’s High Density Tungsten Alloy Radiation Shielding Parts
(1) High Density Shielding
Delivers strong attenuation of penetrating radiation with a density of 16.5–18.8 g/cm³. Compared with traditional lead shielding parts, tungsten alloy reduces shielding thickness and component size by 30%–40% while achieving equivalent X-ray or γ-ray protection performance.
(2) Lead-Free Safety
Eliminates toxic heavy metal contamination during manufacturing and use while meeting environmental and medical safety requirements. Requires no additional protective coating, reducing application and compliance costs.
(3) High Strength and Machinability
Provides high hardness, wear resistance, and deformation resistance with a tensile strength of 700–1000 MPa. Overcomes the brittleness of pure tungsten and enables precision machining of thin-wall components, multi-leaf collimators, and complex shielding structures.
(4) Thermal and Chemical Stability
Maintains dimensional stability under high-temperature and radiation environments with temperature resistance above 1400°C and a low thermal expansion coefficient. Withstands corrosion and repeated high-temperature disinfection and sterilization processes.
(5) Compact Structure and Space Efficiency
Enables compact protection structures through excellent volumetric shielding efficiency. Supports space-limited applications, including syringe shielding sleeves, isotope containers in Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) systems, and industrial non-destructive testing equipment.

3. Applications of CTIA’s High Density Tungsten Alloy Radiation Shielding Parts
(1) Medical Imaging and Radiotherapy
Used in CT scanners, X-ray machines, linear accelerators, and Gamma Knife systems for radiation protection, beam control, and shielding of critical components.
(2) Nuclear Medicine and Radiopharmaceuticals
Used in Positron Emission Tomography (PET) systems, radioactive source containers, and protective sleeves for isotopes such as Tc-99m, I-131, and F-18.
(3) Industrial Inspection
Used in Industrial Non-Destructive Testing (NDT), industrial CT, γ-ray inspection, weld inspection, and pipeline inspection equipment to reduce scattering and improve inspection stability.
(4) Security Inspection
Used in container inspection systems and X-ray security inspection equipment to reduce radiation leakage.
(5) Nuclear Industry and Research
Used for radioactive source protection, reactor systems, particle accelerators, and experimental facilities requiring reliable radiation shielding.
(6) Oil Well Logging
Used as radioactive source protection components in oil drilling and nuclear logging instruments for high-temperature, high-pressure, and corrosive underground environments.
(7) Aerospace
Used in space exploration equipment, avionics systems, and radiation shielding structures requiring compact and high-density shielding materials.
(8) Defense and Military
Used in specialized inspection equipment, protection systems, and radiation shielding structures for high-performance precision equipment.
