TiNi

metal

TiNi is an equiatomic titanium-nickel intermetallic compound and the primary constituent phase in nitinol shape-memory alloys (SMAs). This material is renowned for its exceptional ability to recover from large deformations through thermal or stress-induced phase transformations, making it fundamentally different from conventional metals that yield plastically under load. Engineers select TiNi-based alloys for applications demanding reversible shape recovery, superelasticity (rubber-like behavior without permanent set), or precise actuation control—properties unattainable in standard engineering metals or polymers.
