Description
Nitinol formula is NiTi. by its shape memory and superelastic characteristics, Nitinol is a nickel-titanium alloy distinguished from other materials.it has excellent properties, including kink resistance, biocompatibility and elasticity. the elements it’s composed of—nickel (Ni) and titanium (Ti), Nitinol is a trade name taken from it. nitinol contains these two elements at approximately equal atomic percentages.because of this the nickel content of this alloy has raised great concerns about its usefulness in the medical industry. XOT metals offers nitinol sheet (nickel titanium alloy sheet, shape memory alloy sheet, superelastic alloy sheets) with different Af point, allowing for a customization of alloy compositions, heat treatment conditions, surface finishes, loading plateaus, and tensile strengths.
Shape Memory Alloy (SMA) are one of the most promising smart materials available today, and they can provide the novel solution in several fields and for various applications (e.g. actuator, biomedical application, clamping systems, etc.). Shape Memory Alloys demonstrate a unique ability to recover their initial shape after deformation through a reversible thermo-elastic phase transformation.
Among the commercially available SMA, nickel-titanium (Ni-Ti and Ni–Ti-based) alloys are outstanding due to their excellent performance, reliability, and strain recovery properties. Ni-Ti alloy is attractive for various medical applications due to its biocompatibility, corrosion resistance, and fatigue behavior.

Nitinol Properties
The shape memory and superelasticity properties are the most unique properties of this alloy. The shape memory property allows this metal to “remember” its original shape and retain it when heated above its transformation-temperature. It happens due to the different crystal structures of nickel and titanium. This pseudo-elastic metal also shows incredible elasticity which is approximately 10 to 30 times more than that of any ordinary metal.
Medical Applications
- Nitinol is very useful in dentistry, especially in orthodontics for wires and brackets that connect the teeth. Sure Smile (a type of braces) is an example of its orthodontic application.
- It is also used in endodontic mainly during root canals for cleaning and shaping the root canals.
- In colorectal surgery, it is used in various devices for the purpose of reconnecting the intestine after the pathology is removed.
- Nitinol stents are another significant application of this metal in medicines.
- Its biocompatible properties make useful in orthopedic implants.
- Nitinol wires can be used for marking and locating breast tumors.
- The use of Nitinol tubing for various medical purposes is increasing in popularity.
Industrial Uses
- Nitinol wires are used in model heat engines made for demonstration purposes.
- This material is used in temperature controls. Its shape changing properties can be used for activating a variable resistor or a switch for controlling the temperature.
- This metal is often used in mechanical watch springs.
- It is used as microphone boom or a retractable antenna in cell phone technology for its mechanical and flexible memory nature.
- Nitinol spring is used in various industries for the purpose of utilizing the superelastic properties of this metal.
