Many medical devices use gamma rays to treat tumors. In order to perform accurate radiotherapy and reduce the damage of radiation to patients, gamma ray shielding materials are necessary. Tungsten alloy such as W90Ni10 alloy is a kind of γ-ray shielding material with good absorption to gamma rays.

Tungsten carbide reinforced aluminum matrix composite material is a new radiation protection material. Its γ-ray and neutron shielding performance is more excellent than lead. It also has the advantages of high specific stiffness, high specific strength, excellent plasticity, and high stability. More importantly, it is environmentally friendly. So, this new type of radiation protection material is widely used in medical shielding and other fields.

As a new radiation shielding material, environmentally-friendly and pollution-free tungsten alloy gamma ray shielding material is expected to replace toxic heavy metal lead for the manufacture of medical shields. It is reported that the greater the density, the stronger the ability to attenuate the rays. So, what is the density of a tungsten alloy gamma ray shielding material W94Ni6 alloy prepared by laser rapid prototyping?

Non-toxic and environmentally-friendly tungsten heavy alloy is an ideal anti-radiation material for applying in the field of medical shielding. Tungsten heavy alloy is a ternary alloy composed of 90-98% W and a small amount of Ni, Fe or Cu. There are mainly two series of tungsten heavy alloys including W-Ni-Fe alloy and W-Ni-Cu alloy.
