ASTM F688 This specification covers the chemical, mechanical, and metallurgical requirements for wrought cobalt-35nickel-20chromium-10molybdenum alloy (UNS R30035) in the form of plate, sheet, and foil to be used in the manufacture of surgical implants.
MP35N is a non-magnetic Cobalt-Nickel-Chromium-Molybdenum alloy having an excellent combination of very high strength, excellent corrosion resistance and high fatigue strength. MP35N is used in the construction of heart valve frames for transcatheter heart valve systems. This next-gen alloy has a unique combination of properties that are key to elevating structural heart solutions to new heights:
- High strength: MP35N has unmatched radial strength and ultra-high tensile strength (up to 300 ksi). This strength enhances the performance and longevity of the implants, ensuring heart valves function optimally for years to come.
- Open cell geometry:ASTM F688’s strength supports the intricate open cell geometries critical for cardiovascular devices. Open cell geometries enhance the hemodynamics, or flow of blood, through the valve.
- Good ductility: Heart valves must withstand the repetitive motion of the heart contracting and relaxing. MP35N’s ductility allows heart valve frames to flex without breaking.
- Excellent resistance to corrosion, sulfidation, high-temperature oxidation, and hydrogen embrittlement: MP35N is virtually immune to general, crevice, and stress corrosion in the extreme conditions within the heart.
- Radiopacity: MP35N is radiopaque, allowing for easy visualization during implantation and ensuring precise placement.
MP35N consistently outperforms competing materials used for heart valve stents, offering the optimal alloy choice for designers of cardiac medical devices. Its exceptional properties make it an ideal candidate for structural heart disease solutions—characteristics that are equally valuable in orthopedics, dentistry, and other medical fields. Regardless of the application, it facilitates minimally invasive procedures, enhances biocompatibility, and improves both the patient experience and treatment outcomes.
