The shape memory effect of nickel-titanium alloy (nickel-titanium plate) is based on the change of crystal structure inside it. Nitinol has two crystal structures, namely the martensitic phase at low temperatures and the austenitic phase at high temperatures. At lower temperatures, the alloy is in the martensitic phase, where it is softer and can be bent or machined into various shapes with relative ease. When the temperature rises above a certain transition temperature (austenite end temperature), the alloy will undergo a transition from martensitic phase to austenitic phase. In this process, the alloy "remembers" its original shape and tries to return to that shape.

Nitinol ingot bars are used in the medical device industry (for heart stents, orthopedic implants, orthodontic lines), the aerospace industry (for engine components and spacecraft components), the automotive manufacturing industry (for engine valve springs, shock absorbers and transmission systems), the electronics industry (for microrelays, temperature controllers and thermal sensors), and the energy sector (for solar power generation). Wind turbines).

Nitinol twisted wire has shape memory effect and super elasticity. It can be restored to its original state after deformation. It provides a relatively constant and mild force over a wide range of deformations. In addition, it has good corrosion resistance, making it stable in various environments such as the human body.

Nitinol twisted wire is mainly used in orthodontics. It can provide a continuous and gentle corrective force due to its shape - memory effect and super - elasticity. This kind of force can effectively reduce patients' discomfort and move teeth more physiologically. Also, it has good corrosion resistance and can maintain stability in the complex oral environment.

Compared with ordinary skein, nitinol twisted wire has obvious advantages.
Nitinol has shape memory effect and superelasticity. In the field of orthodontics, an appliance made of nickel titanium wire can provide sustained gentle healing. This force can effectively reduce the discomfort of the patient, and because of its good elasticity, it can maintain a relatively stable corrective force within a large deformation range, so that the tooth movement is more in line with physiological requirements, and the treatment process is more efficient.
At the same time, the corrosion resistance of nitinol twisted wire is strong, and it can maintain good stability in the complex environment of the mouth, and the service life may be longer.

Titanium nickel springs have obvious advantages over other materials.
In terms of elasticity, nickel-titanium springs have superelasticity. It can recover under large strain, the strain can be as high as 8-10% or so, while the ordinary metal spring strain is generally 1-2%, which makes the nickel-titanium spring can still work normally after enduring large deformation.

Shape memory is a unique advantage of nickel-titanium springs. It can remember the original shape, and after deformation, as long as it reaches a certain temperature condition, it can return to the original shape, which is called the "transition temperature".
Nickel-titanium springs also have good corrosion resistance. In complex media such as human body fluids or some chemical environments, it is more resistant to corrosion than springs of materials such as stainless steel, so it is widely used in medical equipment and other fields.
Moreover, the biocompatibility of nickeltitanium spring is very good, after implantation in the human body, the human tissue rejection reaction to it is very small, suitable for making medical implant devices, such as orthodontic dental arch wire.

Shape memory nitinol foil are used as follows:
- Medical instruments: for the manufacture of artificial heart valves, dental orthopaedic wires, fracture fixation devices, etc.
- Aerospace: Engine nozzles, aero engine blades, etc., can be manufactured to withstand high temperature, high pressure and high stress environments with superelasticity.
- Automotive manufacturing: for automotive airbag triggers, engine accelerator pedals, suspension systems and other components;
- Electronic mechanical engineering: electronic connectors, robot joints, micromechanical parts, etc.;
- Daily necessities: such as making bra rings, soft and elastic, can recover shape when close to human body temperature, beautiful and stable shape.

Super elastic nitinol foil has excellent shape memory effect, that is, it can be restored to the original shape after deformation. It also has a high superelasticity, enabling it to withstand large-scale elastic deformation without permanent deformation. In addition, it has good biocompatibility, corrosion resistance and fatigue resistance.

Super elastic nitinol foil can be customized for specific applications. Nitinol alloys have shape memory effects and superelastic properties, which are widely used and can be customized according to different application scenarios and needs.
