1. nitinol ring Properties
1) Chemical composition: Different nitinol alloys have different nickel-titanium ratios, and shape memory nitinol rings are usually 50.9.
2) Shape memory: Nitinol shape memory rings have shape memory, that is, they are shaped into different shapes by applying and releasing stress, so that they can switch between different shapes. This feature makes it widely used in many applications such as medical and automobile manufacturing.
3) Superelasticity: The superelasticity of nitinol rings means that they have elasticity within the percentage range of their deformation, and they can return to their original shape when we use external force to deform them.
4) Strength and corrosion resistance: It has high tensile strength and elastic modulus, and also has excellent corrosion resistance.
5) Plasticity and deformation behavior: Nitinol ring for women has shape memory effect and superelastic behavior, and has good deformation behavior and stable plastic deformation.

5. features of nitinol Alloy ring
1)Bendability: The Nitinol ring can be bent without permanent deformation.
2)Shape Adjustability: The shape of the shape memory nitinol ring can be adjusted by applying and releasing stress.
3)Reduced deformation: The superelastic Nitinol ring alloy can be stressed to maintain its shape, thus reducing the risk of deformation.
6. Processing methods and processes
Common methods of manufacturing nitinol rings are using techniques such as laser cutting, welding and compression molding. The specific process includes:
1)We need to select the appropriate nitinol wire according to customer requirements.
2) We use CAD software to design drawings according to the nitinol ring size required by the customer.
3)We make molds according to the nitinol alloy drawings.
4)We start producing shape memory nitinol rings.
6)Heat treatment processing to shape the superelastic nitinol ring.
7)Clean the surface of the nickel-titanium ring.
