Nitinol Ring

A Nitinol ring is a small, flexible component made from the shape-memory alloy of nickel and titanium. It can change shape when exposed to heat, returning to a predetermined form, which is ideal for applications requiring precise mechanical movement. Nitinol rings are commonly used in medical devices, such as stents, where they expand to fit the shape of blood vessels. These rings also find use in actuators and robotics, providing reliable motion in response to temperature changes. The material’s biocompatibility makes it safe for implantation in the human body. Nitinol rings offer excellent fatigue resistance and durability. Their ability to function in extreme conditions further enhances their usefulness in a variety of industries.
