Nitinol Shape Memory Alloy Wire
Diameter: 1 mm | Activation Temperature (Af): 15–20 °C
Nitinol is a nickel-titanium shape memory alloy that undergoes a phase transformation in its crystal structure depending on temperature. When cooled from its high-temperature austenite phase to the low-temperature martensite phase, it changes shape and returns to its original form when heated above its activation temperature.
Applications
-
Thermal and Electrical Actuators: Used in sensors, thermal valves for fluidics, and autofocus actuators in cameras.
-
Biomedical Devices: Biocompatible, ideal for orthopedic implants, catheters, orthodontic brackets and wires, and neurovascular interventions like stroke thrombolysis.
-
Stents: Collapsible for insertion into arteries or veins, expanding at body temperature to restore blood flow.
-
Structural Engineering: Superelastic Nitinol wires in concrete detect and indicate cracks, providing early warning in bridges and buildings.
Its moderate activation temperature, shape memory effect, and superelasticity make this Nitinol wire highly versatile for medical, mechanical, and structural applications.
