Shape memory of nitiol flat wire is a material property.
Nitinol alloys (including flat wire shapes) have two different crystal structures at different temperatures. At higher temperature, it is the austenitic phase, which has a stable and symmetrical structure. At lower temperatures, it will be transformed into a martensitic phase, which is relatively soft and easy to deform.
When nickel titanium flat wire is processed into a certain shape at high temperature austenitic state, and then cooled to change it into martensitic phase and deformation. Once the temperature rises above the phase transition temperature, the martensitic phase reverses back into the austenitic phase, and the nickel titanium flat wire automatically returns to the original shape it was processed into in the austenitic state.

Application scenario: Medical treatment can be used for dental arch wire, root canal file, medical guide wire. Industry can be used for high-grade composite frames, antennas, fishing gear, jewelry and toys and other industries

The memory effect of nickel titanium wire is activated in the following ways:
Temperature change
- Heating activation: When the nickel titanium wire is heated above a specific phase transition temperature, its internal crystal structure will change to activate the memory effect and return to a pre-set shape, such as the heat-activated nickel-titanium wire in dental orthodontics, the doctor will heat it and bend it into a shape suitable for the patient's teeth, which can produce sustained corrective force at the oral temperature to correct the teeth.
- Cooling activation: Some Nitinol alloys also have shape memory effects activated at low temperatures, but their applications are relatively rare.

Shape memory nitinol ingot are typically produced by first melting and alloying nickel and titanium in a specific proportion. Then, the molten alloy is cast into ingots. After that, through hot - working processes such as forging and extrusion, and followed by cold - working like drawing and machining to get the final nickel - titanium rods with the desired shape and properties.

Nitinol ingot bars are typically produced by first melting and alloying nickel and titanium in a specific proportion. Then, the molten alloy is cast into ingots. After that, through hot - working processes such as forging and extrusion, and followed by cold - working like drawing and machining to get the final nickel - titanium rods with the desired shape and properties.

Nitinol ingot bars can be customized for specific applications. In the medical field, it can be customized according to different treatment needs, such as making medical stents and implants of specific size, shape and performance. In the industrial field, nickel titanium rods with different specifications, strength and corrosion resistance can be customized according to specific engineering requirements for mechanical manufacturing, aerospace and so on. Its customized content includes size, shape, composition, performance, etc., to meet the needs of diverse specific application scenarios such as smart lock core components.
