Medical tungsten alloy radiation shield refers to a shielding part made of high-density tungsten-based alloy with the composition of W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe. During the generation of X-ray radiation in medical treatment, the tungsten alloy radiation shield is an appropriate radiation dose-reducing measure to minimize risk to the patient and the medical team.

Medical tungsten alloy radiation shield is excellent in applications requiring high corrosion resistance, high density, high machinability and high radiation shielding. And the tungsten alloy radiation shield is uniquely homogeneous and does not have any specific directional microstructure. These properties make tungsten alloy an ideal material for use in shielding parts of X-ray tubes, shutter blades of computer tomography equipment, and linear shielding elements of accelerators, etc. Such a radiation shield complies with the "Restriction of Hazardous Substances" standard. So, it is a good idea to replace lead-based materials with non-toxic tungsten alloy materials for many medical device manufacturers.
