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, spring contacts, medical instruments, such as stents and implant electronic connectors, 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.

The measured elongation will be less as thickness decreases to 0.002” and less.
These values may be adjusted by control of process variables – consult HPM for desired values.
