Elastic Niti Nitinol Fishing Wire Black Shape Memory Alloy Ni42crti 3j21 Stainless Steel Shape Nitinol Wire for Medical Devices
The term Nitinol refers to the general term for those NiTi alloys.
Nickel-titanium alloy is a shape memory alloy, which is a special alloy that can automatically restore its own plastic deformation to its original shape at a certain temperature, and has good plasticity.
Its expansion rate is above 20%, its damping characteristics are 10 times higher than ordinary springs, and its corrosion resistance is better than the best medical stainless steel at present, so it can meet the application requirements of various engineering and medicine, and is a very good spring Functional Materials.
In addition to its unique shape memory function, memory alloys also have excellent characteristics such as wear resistance, corrosion resistance, high damping and superelasticity.
Characteristics of Nitinol shape memory alloy
(1) Shape memory
Nickel-titanium alloy shape memory alloy will automatically restore its shape after a certain heat treatment. This change is the shape memory characteristic of nickel-titanium alloy shape memory alloy. Shape memory can be divided into one-way shape memory, two-way shape memory and full-process shape memory according to the recovery status.
(2) Hyperelasticity
Nickel-titanium alloy shape memory alloy will deform when it is subjected to external force, and it will return to its original shape after removing the external force. This is the superelastic characteristic of nickel-titanium alloy shape memory alloy. After the superelastic deformation of nickel-titanium alloy shape memory alloy, it will directly lead to martensitic transformation, and remove the external force, it will lead to reverse martensitic transformation.
(3) Damping
The nickel-titanium alloy shape memory alloy has very good damping properties because of the self-adjustment of the phase transition and the interface and motion generated during the phase transition.
(4) Resistivity
During the deformation process of the martensitic nickel-titanium alloy shape memory alloy, the relationship between the resistance and the strain is linear. When the phase transformation occurs, the slope of the curve will decrease, but the linear relationship will be maintained before and after the martensitic phase.
Application of Nitinol Alloy(1) Couplings, (2) Biomedical and Medical, (3) Toys, Novelty Items, (4) Brakes, 5) Thermal Engines, (6) Sensors, (7) Low Temperature Activated Dies and Memory Slots (8) Lifting equipment.
1. The application of nickel-titanium alloy shape memory alloy in the machinery industry was initially on pipe joints and fasteners
2. Nitinol shape memory alloys can also be used to design vibration isolators
3. Nickel-titanium alloy shape memory alloys can also be used in spacecraft antennas, joints/electromechanical actuators, etc.
4. Nickel-titanium alloy shape memory alloys are mainly used in engine exothermic fan clutches, exhaust nozzles, diesel engine radiators, etc.
Nickel-titanium alloy shape memory alloy has high mechanical properties and biocompatibility, making it widely used in the medical field. Such as orthodontics, plastic surgery, minimally invasive cardiovascular, etc.; the thrombus filter is actually a new product of nickel-titanium alloy shape memory alloy; after the straightened filter is implanted in the vein, it will gradually form a mesh over time. , Prevent more than 90% of blood clots from flowing to the heart, lungs and other organs. In addition, in medical clinical trials, nickel-titanium alloy shape memory alloys are also used in surgical sutures, artificial joints, and artificial hearts.
Over the years, we have worked hard to promote and realize the modernization of alloy sales, and actively cultivated and enhanced the ability of employees' independent innovation. All-round renovation and upgrade of the original business site, facilities and equipment, and modern computer management. Hope to establish long-term partnerships and win market reputation.
