Sandvik Bioline platinum iridium alloys (Pt10Ir, Pt20Ir) are precious metal wires that combine excellent biocompatible properties with excellent radiopacity, moderate strength and good formability. These alloys can be provided in an annealed, stress relieved or coldworked condition depending on the post processing requirements.

For medical use, Sandvik delivers Pt10Ir and Pt20Ir wires with the highest surface finish (Medical class) in order to maximize the fatigue strength which is critical in implant devices such as lead wires for cochlear implants and implant electrodes. Stress relieved conditioned wire are also often required when straightness is critical to the application.

Applications
Sandvik Bioline Pt10Ir and Pt20Ir grades can be used for cochlear implants, stimulated electrodes implants, sensor for continuous glucose monitors and neurological stimulation devices.

These wires can be provided in as drawn condition, annealed or coated with a suitable polymer or PTFE coating.
