What is Nitinol and where is it used?

Nitinol is a nickel-titanium alloy and the most well-known shape memory alloy.

Nitinol is the intermetallic phase NiTi with an ordered cubic crystal structure different from titanium and nickel. It consists mainly of nickel (about 55%), another large part of titanium. The alloy can be used up to 650 °C, is corrosion-resistant and high-strength, but is elastically deformable by up to approx. 8%.

The transformation temperature can be influenced via the alloy ratio. Nitinol alloys with a low transformation temperature of e.g. B. 0 °C are colloquially called superelastic. At room temperature, superelastic material behaves similarly to spring steel or spring wire. Nitinol is often used for surgical tools or implants because of its great malleability and good corrosion resistance, but it is also often used in commercial mechanical engineering.

Nitinol alloys with a high transformation temperature of 80 °C, for example, are colloquially called memory alloys or shape memory alloys. If wires, foils and sheets of this alloy are deformed at room temperature, they take on the bent new shape. If the deformed nitinol is heated above the transformation temperature / AF temperature (austenite finish temperature), it will form back to its original shape. Memory Alloy alloys as well as the super-elastic Nitinol alloy are used. The basic shape of the Nitionol component can be embossed by annealing at approx. 500 °C and a holding time of approx. 20 minutes. We can take over the heat treatment of the Nitinol for you if you decide to buy the NiTi from us.

Common products are Nitinol wire, rod, rod, rod, square, plate, round, electrode, sheet, foil, tape and strip.

We also manufacture Nitinol round and flat springs as well as laser-processed Nitinol foils on customer request.



Sheet and foil made of Nitinol / NiTi alloy as a semi-finished product or end product.

We take care of the processing of Nitinol foil and tape by laser cutting for you as well as the bending of the base material according to the drawing.

Dimensions and transformation temperatures can be selected on customer request and will be discussed individually before purchase.

Before you buy our Nitinol foil and sheets, you benefit from comprehensive advice on application and heat treatment.

Buy Nitinol and NiTi alloy rods and rods in different dimensions.

Nitinol rods and rods are often used in medical technology but also in aerospace and mechanical engineering.

We produce nitinol rods for you on customer request and can therefore respond well to your wishes. You also benefit from a large Nitinol storage so that we can supply you quickly after purchase.

We have Nitinol tubes in different dimensions in stock, but we can also manufacture them according to your wishes.

Buying Nitinol can be easy.

We manufacture nitinol wire according to customer requirements in different thicknesses, tolerances and forming temperatures for your project. Due to its properties, NiTi wire is often used in medical technology, rough travel and mechanical engineering.

Nitinol wire is also often processed into nitinol springs. Our customers often do the further processing themselves. However, we can also produce finished NiTi springs according to your ideas. At the end of this page, the one-way effect and the two-way effect of nitinol are explained, which is of particular interest for the development of nitinol springs.

When purchasing Nitinol wire and Nitinol springs, you benefit from comprehensive advice.

We manufacture Nitinol tape and strips according to customer requirements in different thicknesses, tolerances and forming temperatures for your project. Due to its properties, Nitinol tape is often used in medical technology, rough travel and mechanical engineering.

We take care of the processing of nitinol tapes and strips by laser cutting for you as well as bending the base material according to drawings.

Dimensions and transformation temperatures can be selected on customer request and will be discussed individually before purchase.

The one-way effect of the shape memory alloy Nitinol, also known as NiTi alloy, is understood to mean the return of the Nitinol to its original state when it is heated.

In its cold state, the NiTi alloy has a martensite structure. If the wire, rod or foil is stretched within the strain range of the martensite plateau, the material can be shaped into any desired shape. This shape of the Nitinol component is retained as long as there is no change in temperature. As the component heats up and reaches the austenite start (AS) temperature, the material begins to deform back. The material is restored to its original condition after the austenite finish (AF) temperature is reached. Depending on the NiTi alloy, the AF temperature is between -100 and 150°C.

When the Nitinol component begins to cool, martensite formation begins again. This is completed when the Martensite Finish (MF) temperature is reached. This process of deforming the Nitinol shape memory alloy can be repeated any number of times. We will be happy to bring the Nitinol into the desired shape for you if you decide to buy the NiTi from us.

The Nitinol shape memory alloy two-way effect means the independent deformation of the NiTi material due to temperature changes without the application of force.

The nitinol wire, nitinol foil or nitinol rod remembers its predetermined shape in the low-temperature phase and the shape in the high-temperature phase. This process can be repeated as often as you like and is therefore an interesting effect in the development of sensors and measuring instruments.

The two-way effect of nitinol can be trained in different ways. Of course, we are happy to take over the formation of the component for you if you decide to buy the NiTi, Nitinol from us.
