One limitation is its relatively high cost. Shape memory nitinol wire rope is more expensive than some other materials. Another is that it may have limited resistance to high - temperature environments, which can affect its shape - memory and mechanical properties. Also, its fatigue life under continuous cyclic loading is a concern for long - term applications.

Applications of Super elastic nitinol tube:
- In the medical field, it can be used for stents and catheters.
- In aerospace, it can be used for some special components.
Basic properties of nickel-titanium alloy tube:
- Possesses shape memory property.
- Has superelasticity.
- High corrosion resistance.
- Good biocompatibility.

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.

nickel titanium shape alloy sheet are usually made by the following steps. First, nickel and titanium melt together in a certain proportion to form an alloy. The alloy is then cast into a plate-like shape by a process such as continuous casting or hot rolling. After that, heat treatment is usually performed to enhance and adjust the properties of the material, such as shape memory and superelasticity.

Advantages of nickel-titanium plate: excellent shape memory performance and super elasticity. It can be restored to its original state after deformation.
Application in daily life: for orthodontic line. Due to the elasticity of the wire, it can apply gentle and sustained force to the tooth to correct the position of the tooth. It is also used in some medical stents to help keep blood vessels or other tubular structures open.

Shape memory Nitinol plates have several typical uses. They can be used in flexible displays for better flexibility and impact resistance. In the field of wearables, they have achieved more comfortable and comfortable designs. In addition, due to their unique fluid properties, they have potential use in some soft robots that mimic natural motion.

Shape memory nitinol wire rope is used in medical devices like orthodontic wires due to its shape - memory and super - elasticity. It's also applied in aerospace for its flexibility and resistance to corrosion.

The main challenge of Ni-Ti plate positioning is its shape memory properties. During installation, it may recover its shape unexpectedly due to temperature changes, resulting in inaccurate positioning. Moreover, the nickel-titanium plate is relatively soft, and in a complex working environment, it is difficult to fix it and ensure accurate positioning.

Shape memory nitinol rod have a wide range of applications. In the medical field, it is used in stents and orthodontic wires. A scaffold made from it can be expanded to the appropriate size in the body. Orthodontic wire can apply gentle and sustained force to the tooth during the correction process. In the aerospace field, it is used in some temperature-sensitive components. The alloy can change shape in response to temperature changes, which helps to adjust the mechanism. In everyday life, it is used in glasses frames that can return to their original shape after bending.
