Nitinol shape memory alloy springs

Nitinol shape memory alloy springs also known as Nickel-titanium memory alloy spring is a type of spring made from a shape memory alloy that is primarily composed of nickel and titanium. It exhibits unique properties such as shape memory effect and superelasticity.

There are two types of Nitinol springs:

One-way memory springs can only return to their original shape after being heated above a certain temperature and then cooled down.

Two-way memory springs, which can return to their original shape after being heated or cooled.

Shape memorability
Nitinol springs automatically regain their shape after certain heat treatment, and this change is the shape memory characteristic of Nitinol springs.

Super elastic
The NiTi spring will be deformed when it receives external force and will return to its original shape after the external force is removed, which is the superelasticity of NiTi alloy.

Characteristics:

①Shape memory effect: They can remember their original shape, even after being deformed. This allows them to return to their original shape when heated to a certain temperature.

②Superelasticity: They can undergo significant deformation and still return to their original shape when the load is released. This property allows them to absorb shock and vibration effectively.

③High corrosion resistance: They have excellent resistance to corrosion and are ideal for use in harsh environments.

④High fatigue resistance: It can withstand repeated cycles of deformation without degrading its performance.

⑤Biocompatibility: They are biocompatible, making them suitable for use in medical devices such as stents, orthodontic wires, and other implantable devices.

⑥High strength-to-weight ratio: They are lightweight but have high strength, making them ideal for applications where weight is a concern.

⑦Low hysteresis: They have low hysteresis, which means they can convert heat energy into mechanical energy with high efficiency. This makes them useful in applications where energy conversion is important, such as actuators and sensors.

Application of nitinol springs：

①Medical industry: Niti springs are used in medical applications such as stents, orthodontic wires, and bone fixation devices.

②Aerospace industry: NiTi springs are used in aerospace applications for valves, actuators, and switches.

③Automotive industry: They are used in automotive applications for vibration damping, seatbelt pre-tensioners, and anti-lock brake systems.

④Robotics industry: They are used in robotics applications for grippers, actuators, and sensors.

⑤Consumer electronics industry: They are used in consumer electronics applications such as mobile phones, laptops, and cameras for vibration damping and shock absorption.

⑥Sporting goods industry: They are used in sporting goods such as golf clubs, tennis rackets, and fishing rods for improved shock absorption and vibration damping.

⑦Defense industry: They are used in defense applications such as missiles, torpedoes, and other precision-guided munitions.

⑧Industrial automation: They are used in industrial automation for robotics and automated machinery, providing high force and precise movement.
