Super Elastic Nitinol Memory Alloys Wire, also known as Nickel Titanium (Nitinol or NiTi), belongs to the exclusive class of shape memory alloys. This remarkable wire derives its extraordinary properties from a thermoelastic martensitic phase transformation within the material. Composed of approximately 55%-56% Nickel and 44%-45% Titanium, Nitinol alloys can exhibit significant variations in properties based on slight changes in composition.

This wire can be classified into two primary categories. The first category, known as "SuperElastic," stands out due to its exceptional recoverable strains and resistance to kinking. This makes it highly suitable for applications in orthodontics, such as braces and wires, as well as eyeglasses. On the other hand, the second category, referred to as "Shape Memory" alloys, showcases Nitinol's remarkable ability to revert to a pre-set shape upon heating above its transformation temperature. This characteristic makes it ideal for actuators used in a wide range of mechanical devices.
