Nitinol wire is made from an alloy composed primarily of nickel (Ni) and titanium (Ti), typically in nearly equal proportions, with the nickel content slightly exceeding that of titanium, usually around 55% nickel and 45% titanium. This unique composition endows nitinol with its distinctive properties, such as the shape memory effect and superelasticity.

Shape memory nitinol flat wire Application:
- In medical field, it's used for making stents.
- In electronics, applied to produce connectors.
- For aerospace, utilized in some high-performance components.
- In automotive, helps create reliable parts.
- In daily life, seen in glasses frames.

Nitinol sheets are generally not driven directly by electricity. However, it is possible to use electricity indirectly to drive nickel-titanium plates to exert shape memory effects.
The principle is to increase the ambient temperature around the nickel titanium plate through the current. Since the shape memory effect of the nickel-titanium plate is temperature-related, when the current flows through the heating element (such as the electric heating wire closely connected to the nickel titanium plate), the temperature of the heating element increases, and the temperature of the nickel titanium plate increases.

OEM (Original Equipment Manufacturer) nickel-titanium spring custom size depends on the specific application scenario and customer needs.
The line diameter is generally about 0.05-5mm, the thinner line diameter is used for the scene with low force requirements but high precision, and the thick line diameter is used to withstand the larger force.

In order to make a Ti-Ni1 Super Elastic Nitinol Tube, titanium and nickel are first melted and alloyed in precise proportions. The alloy is then processed by methods such as extrusion or stretching to form a tubular shape. Heat treatment is a crucial step, which involves careful control of temperature to induce hyperelastic phase transition properties. The entire process requires strict control of parameters to ensure the desired hyperelastic properties.

Super elastic nitinol tube basic properties:
- Material composition and performance meet ASTM F2063 and GB24627 standards
- Shape memory characteristics, super elasticity, good corrosion resistance, good biocompatibility;
Super elastic nitinol tube use:
- Medical field vascular stent, orthodontic wire, etc.
- Aerospace as connecting parts, temperature sensitive elements.
- Used in the automotive industry for shock absorption components and sensor components.

Yes, the thickness of Nitinol sheets matters significantly. Thicker sheets are generally less flexible and more rigid, making them suitable for applications requiring structural support and strength. Conversely, thinner sheets are more flexible and can bend more easily, which is advantageous in applications requiring flexibility and conformability, such as medical stents or actuators. Additionally, the thickness of the sheet can affect the rate at which it responds to temperature changes and its ability to exhibit shape memory and superelastic properties. Selecting the appropriate thickness is crucial for the desired performance in specific applications.

A wire similar to nitinol is made from copper-based shape memory alloys (SMAs), such as copper-zinc-aluminum (Cu-Zn-Al) or copper-aluminum-nickel (Cu-Al-Ni). These alloys also exhibit shape memory and superelastic properties but are generally less expensive than nitinol. However, they have lower performance in terms of fatigue resistance and transformation temperatures. Copper-based SMAs are used in less demanding applications, such as actuators, couplings, and temperature control devices. While not as versatile as nitinol, they provide cost-effective alternatives for certain industrial uses.

Superelastic titanium nickel alloy uses:
- Medical: for stents, orthodontic wires, surgical tools.
- Electronics: connectors, sensors, actuators.
- Daily life: Wearing smart clothes and glasses.
- Automotive: In the exhaust system, shock absorbers.

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.

Nickel-titanium shape memory alloy rod has shape memory function, can bend under certain conditions, and then restore the original appearance.
This is because Nitinol undergoes a phase transition when the temperature changes. When the temperature reaches a certain transition temperature, the internal crystal structure can be reversibly transformed, making the material return to its original shape after deformation. However, if excessive bending causes the plastic deformation of the material to exceed its shape memory capacity, it may not be fully recovered.

Shape memory nitinol straight wire have several important applications in the medical field.
One of the main uses is in orthodontics. They are used as archwires in braces. The shape - memory property allows them to exert a continuous gentle force on the teeth, gradually moving them to the desired position. Their elasticity also helps in withstanding the forces exerted during chewing and speaking without easily deforming or breaking.
They are also applied in endodontics. For example, they can be used in root canal treatment as files. Their flexibility enables them to navigate through the complex and narrow root canal systems more easily than stiffer materials, improving the efficiency and accuracy of the treatment.
