Tungsten Screws for Radiopaque Applications

Q: I’m looking for a material that is radiopaque. Do you have any suggestions?
A: Two materials come to mind. First is tantalum. It is often used in medical applications for its radiopacity. Tantalum fasteners are also bio-compatible and extremely corrosion resistant. The second material is tungsten. Tungsten fasteners come in several grades depending on the strength and density needed. Tungsten is extremely dense and radiopaque. It also offers good high strength ranging from 94ksi up to 142 ksi for pure tungsten.
