MP35N® - LTi • UNS R30035

MP35N®-LTi is a nonmagnetic nickel-cobalt-chromiummolybdenum alloy that has excellent corrosion resistance, can obtain ultrahigh tensile strengths (300 ksi) through work hardening and aging, and has good toughness and ductility. Applications include electrical components, springs, and instrument parts in medical, chemical, food processing and marine environments.

After work hardening, MP35N® alloy can be aged in the temperature range of 800/1200°F for increased strength. MP35N® will only respond to aging if in the work hardened condition. Service temperatures up to 750°F are recommended for work hardened material. MP35N® can be successfully TIG welded. MP35N® is produced by double vacuum melting, and as such, has a low nonmetallic inclusion level.

Available Sizes:

MP35N®-LTi is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.030” (0.0127 mm to 0.762 mm) and widths to 5.0” (127 mm). A foil product is available in thicknesses down to 0.0001” (0.00254 mm) and widths of 4.0” (101.6 mm). The material corresponds to UNS R30035.
