Common Applications of Nitinol Shape Memory Wire

Nitinol Shape Memory Wire

A shape memory alloy, Nitinol (Nickel-Titanium Naval Ordinance Laboratory), is an incredibly unique material due to its ability to remember and then return to its original shape after being deformed. This material has been used in various industrial and commercial applications since the 1960s. Today, Nitinol is widely used due to its distinctive shape memory and superelastic properties, making it useful across virtually all industries. In this blog, we’ll explore the most common applications of Nitinol Shape Memory Wire.

What is Nitinol Shape Memory Wire?

Nitinol Shape Memory Wire is a special type of wire made from an alloy of nickel and titanium. As its name implies, this wire is characterized by its ability to hold a memorized shape when heated. When bent or deformed, the Nitinol will return to its original shape upon exposure to heat above certain temperatures. The most interesting feature of this unique wire is that it can be customized to memorize any shape determined by the user, providing many possible applications in medical devices, robotics technology and other engineering designs.

Medical Devices

One of the primary industries where Nitinol is widely used is in the field of medicine. Nitinol’s incredible properties make it ideal for creating highly flexible and durable medical devices. Nitinol is often used to implant stents within the human body to keep arteries and blood vessels open. Nitinol is also used to produce artificial joints and bone staples that provide strength and structure while being more biocompatible than other metallic materials.

Orthodontic Wires

Nitinol has been a game-changer in the field of orthodontics. It is highly preferred over traditional materials, such as stainless steel wires or elastics for braces. They are more comfortable, require fewer adjustments, and provide a better look as they blend in better with teeth. Nitinol has superelastic properties that allow for more minor adjustments that are more comfortable for patients without force.


Nitinol is very lightweight, so it’s perfect for the aerospace industry to reduce weight in components with maximum strength and durability. Nitinol protects temperature-sensitive equipment in the aerospace industry from extreme temperature changes since it can conduct heat more rapidly than other metals. It is used in manufacturing heat sinks, probes, actuators, and other components.


Nitinol is used to develop extra-thin wires and super-sensitive actuators for robotics. Nitinol’s superelastic properties make it incredibly useful for these applications when space is at a premium, as these wires can take the shape of each other while packing without needing to adjust.

Eyeglass frames

Fashion manufacturers have embraced Nitinol for its superelastic properties. Spectacle makers found a way of replacing the traditional and cumbersome hinges, which often break due to the material’s extensive usage. These frames maintain their same shape and are practically unbreakable.


Nitinol Shape Memory Wire is a remarkable material with various applications that can revolutionize various industries. Its unique properties, such as shape memory and superelasticity, make it suitable for creating lightweight, flexible, and durable components in various applications such as medical equipment, orthodontic wires, aerospace, robotics, and eyeglasses. We look forward to seeing further innovation utilizing this exceptional material.
