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.

Wolfmet Tungsten Alloys are not only very dense, but they are also very good at attenuating ionising radiation. This makes them ideal for shielding applications such as in nuclear medicine or in the nuclear industry.

Tungsten Radiation Shielding and Collimators
Wolfmet tungsten is used as a tungsten shield against gamma and x-ray radiation or as a tungsten collimator to focus radiation beams onto a target.
For many years Wolfmet has been the first choice for engineers requiring tungsten radiation shielding or tungsten collimators. One key reason for this is Wolfmet’s very high density; in fact it is more than 60% denser than lead, providing superior attenuation characteristics for x-ray and gamma radiation.
As well as the superior attenuation, Wolfmet’s density also gives designers a significant advantage. It allows them to reduce the thickness of their shields and collimators whilst still providing the same protection as lead which is ideal for applications where space is restricted.
Wolfmet tungsten alloy can be machined with conventional CNC machines, allowing our team to manufacture a wide range of designs to customer requirements. Once in use Wolfmet is physical strong and dimensionally stable up to 1000°C, making it robust and long lasting. In addition, Wolfmet is easy to clean and non-toxic so there is no need for licensing or special handling precautions.
Now we can also manufacture collimators using Wolfmet 3D – our innovative additive manufacturing process. We build components by fusing successive layers of pure tungsten. There are many benefits of using this process including the production of highly complex component designs, geometries not possible with traditional milling and turning and reduced scatter due to denser septa resulting in more accurate images than with traditional lead collimators.
We can produce xxx, coded apertures / coded-aperture masks, xx, xx, xx

As well as Wolfmet tungsten being an excellent shielding material the Wolfmet team at M&I Materials has a wealth of engineering knowledge and manufacturing experience. This helps us to work in partnership with customers to provide the perfect bespoke tungsten radiation shielding solution, where off the shelf items will not meet requirements.
