Built for transformation, our shape memory Nitinol offers repeatable, reliable performance where precision matters most. Categorized as warmer grades of Nitinol, shape memory is more appropriate for use in high-temperature industrial applications. Shape memory grades are also widely used in Nitinol actuators.
Shape memory isn't limited to use in industrial applications. Designs often leverage phase transformation at body temperature (37°C [98.6°F]), making shape memory Nitinol useful for medical devices.
Shape memory grades
NiTi #5 and #6 are commonly used in high temperature actuators, including locking/latching systems and vents/valves.
NiTi #8 is typically used in applications that require a phase transformation at body temperature.
All binary Nitinol grades meet the chemistry requirements set forth by ASTM F2063 for use in surgical implants.
