MP35N® is an age-hardened, nonmagnetic, biocompatible cobalt-nickel-chromium alloy with molybdenum added for corrosion resistance. It is often triple-melted to insure purity, stability, and overall performance. This is achieved by adding an electroslag remelt (ESR) in between the typical vacuum induction melt (VIM) and vacuum arc remelt (VAR).
Among its uses in the medical industry are:
- Orthopedic wires and cables
- Catheters
- Pacing lead wire conductors
- Stylets and probe wires
MP35N® is also referred to as:
- UNS R30035
- ASTM F562
- 35Co-35Ni-20Cr-10Mo
- NACE MR-0175
