NiTinol: A Review of its Smart Properties that Make it a Smart Alloy and a Strong Ally in Endovascular Neurosurgery

Indian Journal of Neurosurgery
Nitinol is an equiatomic alloy of nickel and titanium. Its unique properties like “superelasticity” and “shape memory” have made it one of the most commonly used materials for manufacturing hardware in endovascular neurosurgery.

Superelastic Nitinol: The Frontiers of Lifetime Prediction

, 2016
While superelastic Nitinol exhibits only mediocre performance in load-controlled fatigue, its durability in displacement-controlled fatigue is unsurpassed amongst metals. For this reason, it is often used in medical applications in which the native anatomical compliance must be preserved and consequently, where no other metal can survive.
