Nitinol, also known as memory alloy or superelastic alloy, is a special alloy material composed of nickel and titanium elements.

One of the most notable features of NiTi alloys is the shape memory effect. Within a specific temperature range, it can remember a predetermined shape and be able to return to its original shape when activated by external heat or stress. This makes nickel-titanium alloys widely used in medical devices, aerospace, automobiles and electronics.

Nitinol also has excellent superelastic properties. It can return to its original shape after being deformed by stress and has a large elastic deformation range. This property makes it widely used in the manufacturing of springs, torquers, anti-shock devices and eyeglass frames.

The good corrosion resistance of nickel-titanium alloy can resist the erosion of many corrosive media, including acids, alkalis and salt water. Therefore, it also has important applications in fields such as marine engineering, chemical industry, and oil extraction.

Nitinol has good high-temperature stability and can maintain its shape memory and superelastic properties in high-temperature environments. This makes it very valuable in high temperature applications in the aerospace sector.

Recently, nickel-titanium alloys, shape memory alloys with temperature-changing characteristics, have come into public view because when the shape memory alloy is heated to a specific temperature, it will undergo a phase change and thus return to its memorized shape. This metal is used to make flower shapes, which are in a closed state under normal conditions and gradually return to the open state by raising the temperature. It is called the iron tree blooming by the public.

Nitinol alloys are designed in many fields, and their special properties make them widely used in medical, automotive, electronics, construction and other fields. This design and creation of nickel-titanium flowers not only allows the public to understand the characteristics of this metal, but also opens up new directions for nickel-titanium metal in art, decoration, etc., making nickel-titanium metal more popular for the public.
