NiTi (nickel-titanium alloys)

NiTi, or nickel-titanium alloy, is a metal known for its unique ability to return to its original shape after deformation, a property called shape memory. It is highly flexible, durable, and can withstand repeated bending without breaking. NiTi also exhibits superelasticity, allowing it to stretch significantly and recover instantly. These qualities make it ideal for applications like medical devices (e.g., braces and stents), robotics, and flexible engineering components. Its properties stem from its special crystalline structure, which changes with temperature or stress, enabling it to reliably transform shape under various conditions.
