Nitinol wire is a unique nickel-titanium alloy that "remembers" its original shape.Unlike standard titanium, Nitinol exhibits extraordinary superelasticity and shape memory effects triggered by temperature changes.
Whether you are developing life-saving medical stents or high-tech actuators for aerospace, our Nitinol wire provides the consistent Austenite Finish temperatures and mechanical reliability your project demands.

FAQ
Q: What is the difference between Superelastic and Shape Memory wire?
A: Superelastic wire is "springy" at room temperature and is used for flexibility. Shape Memory wire is "soft" at room temperature and only returns to its shape when heated.
