Nickel titanium alloys have been widely used in various fields due to their unique properties such as shape memory effect, superelasticity, corrosion resistance, and biocompatibility. The main scenarios are as follows:

1. Medical device field

Interventional therapy equipment: This is one of the core application scenarios of nickel titanium alloy. For example, vascular stents, utilizing their superelasticity and shape memory properties, can be compressed to a very small diameter and inserted into blood vessels. Upon reaching the lesion site, the stent returns to its predetermined expanded shape at body temperature, supporting narrow blood vessels; There are also esophageal stents, biliary stents, etc., which have similar principles and are used to clear blocked cavities.

Orthodontic materials: Nickel titanium alloy wire used for orthodontics, with its super elasticity, can generate sustained and gentle orthodontic force, and can adapt to the complex movement trajectory of teeth. Compared with traditional metal wire, it is more comfortable and the orthodontic effect is more stable.

Minimally invasive surgical instruments, such as biopsy forceps and grippers for laparoscopes and endoscopes, can achieve precise opening and closing movements using their shape memory characteristics. The materials are thin and flexible, which can reduce surgical trauma.

Orthopedic implants: Some orthopedic plates, intramedullary nails, etc. utilize shape memory effect to better fit the bone shape, improve fixation effect, and reduce the risk of postoperative rejection due to biocompatibility.

2. Aerospace field

Intelligent structural components: used to manufacture deployment mechanisms for satellites, such as brackets for solar panels, antenna brackets, etc. During launch, these brackets can be folded and stored to save space. After entering space, they trigger the shape memory effect through temperature changes and automatically unfold into a working state.

Pipeline connector: A pipe joint made using its shape memory characteristics, which can expand at low temperatures during assembly. After being fitted onto the pipeline interface, it will shrink and tighten when the temperature rises to room temperature, achieving a sealed and vibration resistant connection with much higher reliability than traditional joints.

3. Daily consumption and industrial sector

Glasses frame: The super elastic nickel titanium alloy glasses frame is not easily deformed, and can quickly return to its original state even if it is greatly bent. It has strong durability and is lightweight, making it more comfortable to wear.

Intelligent temperature control components: such as automatic window openers for greenhouses, overload protectors for circuits, etc. By triggering the shape memory of the alloy through temperature changes, automatic switching or power-off can be achieved without the need for additional power devices.

Anti scald valve: In equipment such as water heaters and coffee machines, when the water temperature exceeds the set threshold, the nickel titanium alloy component will change shape and automatically close or adjust the valve to prevent scalding.
