H.C. Starck MP35N® Nickel/Cobalt/Chromium/Molybdenum Alloy

MP35N is a nickel-cobalt based alloy of the Multiphase® alloy system that has ultra high strength, toughness, ductility, biocompatibility, and outstanding corrosion resistance. H.C. Starck offers MP35N alloy in flat rolled plate, sheet, and foil products. MP35N is produced by vacuum induction melting and consumable vacuum arc re-melting. Strengthened by work hardening and aging to levels of 260 to 300 ksi (1790 to 2070 MPa), MP35N has good ductility with greater than 40% reduction in area, and good toughness. MP35N can be effectively utilized at cryogenic temperatures without embrittlement and up to 600°F without loss in performance. The high strength and corrosion resistance, high modulus, ease of fabrication, and other mechanical properties make MP35N an ideal candidate for high performance products, where emphasis is placed upon dependability for demanding applications.

MP35N products are used in diverse applications:

• Biomedical uses: Orthodontics and Prosthetics
• Oil Industry, Chemical and Marine equipment – Valve components, springs, high pressure door dogs
• Aircraft and Aerospace components – Springs, leading edge strips
• High Pulse Magnet Research
