Nitinol Wire SE & SMA Nitinol FAQ
What is Nitinol?
A: Nitinol is a metal alloy comprised of nearly equal parts of nickel (Ni) and titanium (Ti). Its name is an acronym for Nickel Titanium Naval Ordnance Laboratory, where it was discovered in the late 1950s by William J. Buehler . It is the most widely used commercial shape memory alloy (SMA).
What makes Nitinol “smart”?
A: Nitinol is considered a “smart” or “intelligent” alloy because it can exist in two different temperature-dependent crystal structures (phases) and remember a pre-programmed shape . This allows for two unique properties:
Shape Memory Effect (SME): The alloy can be deformed at a low temperature and will return to its original, “programmed” shape when heated above a specific temperature .
Superelasticity (or Pseudoelasticity): At higher temperatures, the alloy can be deformed significantly (up to 8-12%) and will instantly snap back to its original shape when the stress is removed, much like rubber but with the strength of metal
What is “Active Af” vs. “Fully Annealed Af”?
A: This distinction is crucial for buyers .
Fully Annealed Af: The transformation temperature of the material in its softest, most homogeneous state (e.g., ingot level).
Active Af: The actual transformation temperature of the material in its final product form (e.g., a wire that has been cold-worked and heat-treated for superelasticity). For a superelastic wire, the Active Af is typically set just below room or body temperature (e.g., 0°C to 15°C) to ensure superelastic behavior at the use temperature .
