Nitinol Shape Memory Alloy Sheet
Thickness: 0.5 mm | Activation Temperature (Af): 80–85 °C
Nitinol is a nickel-titanium shape memory alloy that undergoes a phase transformation depending on temperature. When cooled from its high-temperature austenite phase to the low-temperature martensite phase, it deforms, and upon heating above its activation temperature, it returns to its original shape.
Applications
-
Thermal and Electrical Actuators: Functions as sensors and actuators in thermal valves for fluidics or autofocus mechanisms in cameras.
-
Biomedical Devices: Highly biocompatible, suitable for 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, providing early warning in bridges and buildings.
The high activation temperature of this sheet makes it ideal for applications requiring robust thermal actuation and shape memory response under elevated temperatures.
