Nitinol
Nitinol is a metal alloy, sometimes also called Shape Memory Alloy (SMA). Nitinol alloys exhibit two closely related and unique properties: shape memory and superelasticity. Shape memory refers to the ability of a material to undergo deformation at one temperature, and then recover its original shape upon heating above its "transformation temperature". Superelasticity occurs in a narrow temperature range just above the transformation temperature; in these conditions, no heating is necessary to return to the pre-deformation shape.
Shape Memory Alloys (SMAs) have been considered as one of the most promising smart materials. They can provide novel solution in several fields, for various applications (e.g. actuator, biomedical application, clamping systems, etc.). Among the commercially available Shape Memory Alloys, nickel titanium ones are outstanding due to their excellent performance and reliability. In addition to its strain recovery, Nitinol is attractive for medical applications due to its biocompatibility, corrosion resistance and fatigue behavior.
Shape Memory Alloy Type
| Type | Description |
| Two-way Shape Memory | Alloy that restores high-temperature shape when heated, and restores low-temperature shape when cooled |
| One-way Shape Memory | Alloy deforms at sub-transformation temperatures and restores pre-deformation shape when heated, demonstrating unidirectional memory behavior. |
Glossary
Shape Memory Effect
"Shape Memory" describes the restoration of the original shape of a plastically deformed sample upon heating.
Superelastic Effect
An elastic (reversible) responses to an applied temperature, caused by a phase transformation between the austenitic and martensitic phases of a crystal.
Ms- Initial temperature for an austenite to martensite transition
Mf- Final temperature for an austenite to martensite transition
As- Initial temperature for a martensite to austenite transition
Af- Final temperature for a martensite to austenite transition
Nitinol products we provide:
Nitinol Rolling Products: Nitinol Sheet, Nitinol Strip, Nitinol Foil
Nitinol Drawing & Swaging Products: Nitinol Wire (Super elastic Nitinol Wire, Shape Memory Wire), Nitinol Rod, Nitinol Fishing wire
Other custom parts: Nitinol Spring, Nitinol Parts
Shape memory gives Nitinol the ability to be deformed at one temperature, and then return to its original shape when being heated to its transformation temperature. This effect is caused by the material changing from its low temperature monoclinic martensitic structure to the high temperature cubic austenitic structure.
Besides nitinol shape memory alloy, we can also provide TiNiCu and TiNiNb shape memory alloys.
