Nickel Titanium (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. Typically composed of 55%-56% Nickel and 44%-45% Titanium, even minor compositional adjustments can significantly alter its performance characteristics.

Primary Categories of Nitinol:

• SuperElastic: Known for exceptional recoverable strains and superior kink resistance. Commonly utilized in orthodontics (braces, wires) and eyeglass frames.
• Shape Memory: Valued for its ability to recover a pre-set shape upon heating above its transformation temperature. This makes it ideal for actuators and various mechanical devices.
