Product Specifications

Nitinol coil spring have shape memory and super elastic spring materials. It is composed of an alloy of nickel and titanium, with high elastic modulus and high resilience, and can be restored to its original form after deformation. This alloy material is widely used in medical, aviation, automotive, machinery manufacturing and other industries, in the medical field, tungsten titanium springs are used to manufacture medical devices such as brackets, teeth molars. In the aviation field, it is used to make aircraft landing gear shock absorbers, mainly because of its high strength and high heat resistance. In the automotive sector, it is used to make components such as valve springs, transmissions, and suspension systems. In general, nickel-titanium spring has good plasticity, corrosion resistance and oxidation resistance, and has a wide range of application prospects.

Technical Features

Shape Memory Effect: Nitinol, a unique alloy of nickel and titanium, possesses the remarkable ability to return to its original shape after being deformed when exposed to heat. This characteristic is not only fascinating but also opens up innovative solutions in diverse applications, such as medical devices, where implants can adapt to specific anatomical shapes and restore functionality without additional procedures.

Superelastic Properties: One of Nitinol's standout features is its superelasticity, allowing the material to endure substantial deformation while effortlessly reverting to its original shape. This property is particularly advantageous in dynamic applications, such as in robotics and aerospace, where components must withstand significant stress and strain while maintaining their integrity and performance.

Corrosion Resistance: In addition to its mechanical properties, Nitinol is renowned for its exceptional corrosion resistance. This characteristic ensures that it remains reliable and effective in various environments, including harsh or corrosive conditions. As a result, Nitinol components not only exhibit longevity but also require less maintenance, making them a preferred choice in industries like biomedical and aerospace engineering.

Nickel-titanium spring use method
1. Storage of nickel-titanium spring: storage should avoid pits or scratches on the surface or central part of the spring, so as not to affect the use effect, storage should be placed in a dry, well-ventilated environment, and properly packaged.

2. Installation of nickel-titanium spring: The installation of nickel-titanium spring should try to ensure that the axial position of the spring is correct, do not distort or deform the spring, so as not to damage the texture of the spring surface. Apply lubricant to surfaces in contact with other components to reduce wear.

3, the use of nickel-titanium spring: when using nickel-titanium spring should try to avoid exceeding its elastic limit, so as to avoid abnormal bending and deformation. After normal use, the spring should be regularly checked for fatigue cracks, deformation or surface wear.

4. Maintenance of nickel-titanium spring: clean and maintain the spring regularly, maintain a dry and ventilated environment, and prevent corrosion of the spring surface. At the same time, pay attention to avoid overuse and long-term non-use, so as not to affect the service life.
