Radiation shielding and collimators

The high density of Wolfmet tungsten alloy is a key reason for its superior radiation attenuation characteristics which make it ideal for use as shielding and collimators. Physically strong and dimensionally stable up to 1,000°C, Wolfmet tungsten alloy is robust and long lasting. It requires no licensing or special handling precautions.

We also produce components using our additive manufacturing process – Wolfmet 3D. It offers benefits when manufacturing high-precision components such as collimators and radiation shields in imaging systems.

With more than 40 years’ experience in manufacturing tungsten for the nuclear industry, Wolfmet offers a wealth of engineering knowledge and expertise to support customers in creating bespoke radiation shielding solutions.


Radiation can be used for both diagnostics and therapeutic applications in nuclear medicine. In each case, Wolfmet tungsten alloy provides the perfect solution for radiation shielding and collimators.

Recent pre-clinical studies have shown that Wolfmet 3D printed tungsten collimators produce dramatically improved image quality.
