Nitinol Shape Memory Alloy Wire
Diameter: 1 mm | Activation Temperature (Af): 45–50 °C
Nitinol is a nickel-titanium shape memory alloy that undergoes a phase transformation with temperature changes. When cooled from its high-temperature austenite phase to the low-temperature martensite phase, it can be deformed, and upon heating above its activation temperature, it recovers its original shape.
Applications
-
Thermal and Electrical Actuators: Serves as sensors or actuators in thermal valves for fluidics or autofocus mechanisms in cameras.
-
Biomedical Devices: Biocompatible for use in orthopedic implants, catheters, orthodontic brackets and wires, and neurovascular interventions like 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’s activation temperature range makes it suitable for medium-temperature actuation applications and biomedical devices requiring body-temperature responsiveness.
