1.What is the shape memory effect in Nitinol wire?
The shape memory effect allows the NiTi alloy to be deformed in its martensite phase and recover its original austenite shape when heated above the transition temperature, generating significant force ideal for actuators.
2.How do I activate the Nitinol wire?
Activation occurs by heating via electrical current (Joule heating), hot water, or ambient temperature rise. For 1.0mm shape memory wire, response time depends on current and cooling method.
3.Can I retrain the shape of this Nitinol SMA wire?
Yes! Heat the wire to approximately 500°C while constrained in the desired shape, hold for 10-45 minutes (depending on diameter), then quench in water to set the new shape memory.
4.What is the typical transition temperature for this wire?
Transition temperatures vary; common ranges are 40-90°C for actuation. Specify your needs for customized Af temperature in Nitinol actuators.
5.Is this Nitinol wire superelastic?
Primarily focused on shape memory effect, it also exhibits superelasticity at higher temperatures, allowing recovery from strains up to 10% without deformation.
6.How durable is 1.0mm Nitinol wire in repeated cycles?
With proper design (avoiding overstress), it supports high cycle life (up to millions), thanks to excellent fatigue resistance in shape memory alloys.
7.What safety precautions should I take?
Nitinol is biocompatible and non-toxic, but avoid overheating above 150°C to prevent damage. Use appropriate current limits for electrical activation in sensors and actuators.
