Nickel Titanium (also known as Nitinol or NiTi) belongs to a unique class of shape memory alloys. Its extraordinary properties are derived from a thermoelastic martensitic phase transformation within the material.

Nitinol alloys are typically composed of 55%-56% Nickel and 44%-45% Titanium. Even small adjustments in this composition can significantly impact the material's overall performance and characteristics.

Primary Categories of Nitinol:

• SuperElastic: Characterized by extraordinary recoverable strains and kink resistance. It is widely used for orthodontics (braces, wires, etc.) and high-end eyeglasses frames.
• Shape Memory: Valued for its ability to recover a pre-set shape when heated above its transformation temperature. This makes it ideal for actuators and various mechanical devices.
