Advantages of Tungsten Alloy As Medical Shielding Material

Tungsten alloy has the advantages of high density, good machinability, good corrosion resistance, high radiation absorption capacity and high strength. Widely used in aerospace, automotive industry and radiation shielding and other fields.


Tungsten alloys are best suited for applications that require a large amount of weight to be packed into the smallest possible space. The density of tungsten is about 1.7 times that of lead, the traditional shielding material. The radiation shielding performance of a material is closely related to the density of the material. Higher density means better radiation absorption and radiation shielding capabilities. Therefore, it provides a higher degree of shielding. Lead alloy is a preferred medical shielding material.


This is a viable option for situations where lead cannot be applied. The advantages of tungsten alloys include reduced size and maximum weight in large or small cavities for radiation shielding. It is powerful and highly customizable as precision components. The high specific gravity tungsten alloy shield has better shielding performance for gamma rays, which can reduce the volume of the shield. Compared with lead, the same volume of high specific gravity tungsten alloy shield has better radiation shielding performance. In addition, since tungsten alloy is non-toxic and non-polluting, it is more environmentally friendly than lead and depleted uranium. To prevent exposure, lead encapsulation or coating may be required.


All in all, tungsten alloy is the material of choice for medical and industrial environments where radiation shielding is required because it uses less material than lead to provide the same level of absorption. Tungsten is an excellent medical shielding material, ensuring minimal radiation exposure and ensuring the "as low as reasonably possible" principle in the workplace. Processability, radiographic density, strength, low toxicity and heat resistance provide excellent design flexibility compared to other shielding materials. Because tungsten alloy has high density (density is 60% higher than lead), machinability, good corrosion resistance, high radiation absorption capacity (better than lead and steel), high strength, it is the best raw material for shielding parts. Tungsten alloy shields still have the same radiation shielding ability as lead, although the volume and thickness of tungsten alloy shields are reduced.
