Custom Tungsten Heavy Alloy Solutions for Nuclear Medicine
Our Densram® Tungsten Heavy Alloys (ranging from 90% to 97% Tungsten) are the preferred choice over traditional lead for modern nuclear applications.
- Maximum Protection, Minimum Volume: With a density up to 18.5 g/cm³, Densram® provides equivalent shielding to lead with significantly less bulk—ideal for compact medical devices.
- Exceptional Machinability: Unlike lead, which is soft and difficult to machine precisely, our tungsten alloys allow for tight tolerances and complex threading, ensuring a perfect fit for your assembly.
- Non-Toxic & Sustainable: Densram® is a "green" material. It is non-toxic and does not require the special handling or environmental protections associated with lead.
- Certified Quality: Our production processes are certified to EN 9100 (Aerospace and Defense standards) and ISO 9001, ensuring the traceability and reliability required for nuclear technology.
