Forming memory wire nitinol involves: Shaping: Bend or twist the nitinol wire into the desired shape using tools or fixtures. Heat Treatment: Heat the wire above its transformation temperature, typically between 450°C and 550°C (842°F to 1022°F), for a few minutes to set the shape. Quenching: Rapidly cool the wire in water or air while maintaining the shape to lock in the memory effect. Verification: Test the wire to ensure it retains the shape and exhibits the desired shape memory and superelastic properties. This process ensures that the nitinol wire will return to its pre-set shape when heated.

The temperature of nitinol wire refers to its phase transformation temperature, which determines its shape memory and superelastic properties. At higher temperatures, above the austenite finish temperature (Af), nitinol exhibits superelasticity, returning to its original shape after deformation. Below the martensite start temperature (Ms), it remains in a deformed state until heated above Af. These temperature-dependent behaviors enable precise control of nitinol's mechanical properties, making it ideal for applications like medical stents and actuators, where responsive and reliable performance is essential.
