Nitinol bracelet, we also call it shape memory nitinol bangle. It is made of nitinol round wire or nitinol flat wire. Our company has built a design team specifically for nitinol jewelry, which can customize various popular jewelry according to the customer's style and size. It is also very popular in the jewelry industry because nitinol bangle has the following advantages:
1. It can restore its shape before deformation after deformation.
2. It has good compatibility with human skin, so it can meet the application needs of various jewelry and medicine, and is a very excellent functional material.
3. Grey nitinol bracelet utilizes the superelasticity of nitinol alloy. Superelastic shape memory alloy bangle can exhibit the so-called mechanical shape memory effect, or apparent superelastic deformation performance. This deformation can be up to 96 times the elastic strain of steel. Superelasticity is caused by the stress-induced transformation of austenite to martensite. After the stress is eliminated, it can completely return to its original shape.
Nitinol bracelet is widely used in many fields such as the jewelry industry and the medical field due to its excellent performance.

The production process of super elastic Nitinol bracelet
1. Material selection: First, we need to choose nickel titanium round wire or flat wire with good flexibility to meet the durability of nitinol bangle.
2. Cutting: We cut the selected superelastic nitinol wire into appropriate lengths.
3. Forming: Use professional machines to shape the nitinol strip material of appropriate length into the shape of NiTi bangle, and ensure that each bending point has the required memory.
4. Heat treatment: Put the finished shape memory nitinol bracelet into a special heat treatment equipment, heat and cool it according to certain time and temperature conditions to adjust the austenite phase and thermal memory effect of the material.
5. Surface treatment: Put the finished superelastic nitinol bracelet into water to wash off the surface oil to keep the surface clean.
6. Inspection and quality control: All nickel titanium bracelets are quality controlled and inspected to ensure that they meet product standards and quality requirements.
7. Package: The products are beautifully packaged, marked with sizes, and properly transported and stored.
Nitinol memory bracelets use materials with very high apparent elasticity and ornamental elasticity without causing any permanent strain, which gradually improves the commercial value of nickel-titanium memory alloys. This metal has a very broad prospect in the jewelry market. If you want to know more about nickel-titanium bracelets, please feel free to contact amybai2010@zwmet.com or 0086-18161909780 (WhatsApp)
