Super elastic nitinol rod is a superelastic material, also known as memory alloy material, which is an alloy composed of nickel and titanium. This material has very good elasticity and corrosion resistance but also has shape memory properties. It can be heat-treated to control the temperature at which it returns to its previous shape, making it useful in medical devices, aerospace, car manufacturing, and other industries. Superelastic nitinol rod also has excellent low-temperature performance and can be used in extreme temperature environments, so it is widely used in fields such as space exploration and deep sea exploration.

Super elastic nitinol rod is a shape memory alloy made of nickel and titanium. Its working principle is based on the shape memory and superelastic properties of the material, which means that it can recover its original shape through deformation under different temperatures and stress conditions.

 

At high temperatures, the super elastic nitinol bar becomes soft and can be manually bent and shaped. When it is cooled and pressure is applied, it returns to its original shape. This is because the pressure changes the state of the electrons, which changes the crystal structure of the material.

 

The material's superelastic properties are due to its unique crystal structure. It can deform under strain without leaving residual strain, making it ideal for applications in fields such as medical, aerospace, and mechanical engineering.

 

Super elastic nitinol bar is a special alloy material consisting of nickel and titanium. It has superelasticity and shape memory effect, so it has a wide range of applications in fields such as medical treatment and aerospace.

 

In the medical field, superelastic nitinol rod is used as artificial prosthesis, such as heart stents and arterial narrowing correctors. In addition, it can be used in dental aligners and ophthalmic surgical instruments.

 

In the aerospace field, super elastic nitinol rod can be used to manufacture various components such as guides, valves, springs, and spacecraft components. It's corrosion resistance and fatigue resistance make it ideal for use in these extreme environments.
