Nitinol Shape Memory Alloy Wire
Diameter: 2 mm | Activation Temperature (Af): 80–85 °C
Nitinol is a nickel-titanium shape memory alloy that undergoes a reversible phase transformation with temperature changes. When cooled from its high-temperature austenite phase to the low-temperature martensite phase, it can be deformed. Upon heating above its activation temperature, it returns to its original shape.
Applications
-
Thermal and Electrical Actuators: Functions as sensors or actuators in thermal valves for fluidics and autofocus mechanisms in cameras.
-
Biomedical Devices: Highly biocompatible for orthopedic implants, catheters, orthodontic brackets and wires, and neurovascular interventions such as stroke thrombolysis.
-
Stents: Collapsible for insertion into arteries or veins; expands at body temperature to restore blood flow.
-
Structural Engineering: Superelastic Nitinol wires in concrete detect and indicate cracks in bridges and buildings.
This wire, with a high activation temperature, is suitable for high-temperature actuation applications, advanced biomedical devices, and structural monitoring in engineering projects.
