Shape Memory Alloys

Shape Memory Alloys are smart metallic materials that can return to their original shape after mechanical deformation or thermal stimulation. This unique behavior is mainly driven by the transformation between austenite and martensite phases, allowing SMAs to provide shape recovery, pseudoelasticity, and controlled movement in engineering applications.

Shape memory alloys are commonly produced in NiTi-based, Cu-based, Fe-based, and NiAl-based compositions. Among these, NiTi shape memory alloys are widely preferred due to their high recoverable strain, stable performance, and functional reliability.

What Are Shape Memory Alloys Used For?

Shape memory alloys are used in applications that require compact actuation, reversible deformation, and reliable mechanical response. Key application areas include automotive systems, aerospace components, robotic actuators, sensors, biomedical implants, braces, and medical devices.
