Nitinol Shape Memory Alloy Sheet
Thickness: 2 mm | Activation Temperature (Af): −10 to −15 °C
Nitinol is a nickel-titanium shape memory alloy that undergoes reversible phase transformations depending on temperature. When cooled from its high-temperature austenite phase to the low-temperature martensite phase, it can be deformed. Once heated above its activation temperature, it recovers its original shape.
Applications
-
Thermal and Electrical Actuators: Used as sensors or actuators in thermal valves for fluidics or 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 sheet, with a low activation temperature, is ideal for applications requiring actuation at subzero temperatures and for specialized biomedical and structural monitoring uses.
