Low cobalt for EU MDR compliance

The landscape of the industry is changing with the new European Union medical device regulations (EU MDR). Essentially cobalt-free stainless steel compositions address the up-classification of cobalt as a Class II RMR substance.

Low nickel for patient sensitivities

Exposure to nickel ions released from the normal wear of medical implants can lead to adverse effects for patients sensitive to the metal. BioDur® 108 offers an FDA-approved, essentially nickel- and cobalt-free alternative to other stainless options. Advanced cold-work capabilities allow us to tailor the mechanical properties of BioDur 108 B and C, 316LS, and 465 to specific end uses.

Large-scale nitinol device production

Nitinol is widely used in medical devices due to its superior superelasticity, shape memory effect, low stiffness, damping, biocompatibility, and corrosion resistance. Our Nitinol AM solution empowers large-scale production of complex device geometries with pre-designed porosity, homogeneous composition, high density, and near net shape — all with little to no post-processing.
