What is Shape Memory Alloy Nitinol

After Russia pledged to scale back its military operations around Kyiv and in northern Ukraine, the prices of most industrial metals fell, led by aluminum, showing people’s concerns for supply shortage eased.

At an earlier time, the West imposed sweeping sanctions on Russia for its invasion of Ukraine, which aroused concerns about the supply problem because Russia is a major producer of nickel, aluminum, and copper. 

Russia is also a major gas supplier to Europe, where potential supply disruptions are seen as hitting power-intensive aluminum and zinc Nitinol are still very uncertain.

What is Nitinol?

Nitinol is a shape memory alloy, which is a special alloy that can
automatically restore its own plastic deformation to the original shape at a
certain temperature, and has good plasticity. In addition to its unique shape
memory function, memory alloys also have excellent characteristics such as wear
resistance, corrosion resistance, high damping and superelasticity.

Nickel-titanium alloy has a strong “memory”, it can accurately restore its
original shape with the change of temperature, use it to fill teeth, and even
the frog holes that you have twisted around can be inlaid very tightly; use it
to When connecting the pipes, it will be like the tight hoop on Sun Wukong’s
head, which can shrink automatically and is very firm.

Uses of Nitinol

The pipe joint device made of nickel-titanium alloy can automatically shrink
when heated, so the pipe joint can connect the catheter very firmly. This kind
of pipe joint is used in the system of naval ships and some chemical devices.
Many countries use shape memory alloys to make self-fastening rivets to fasten
the connection of some special parts such as aircraft and spacecraft. The United
States also uses shape memory alloys to develop an antenna that opens
automatically in a spacecraft. This antenna can be automatically folded and put
into the spacecraft. As the flight altitude rises, the temperature rises under
the sunlight, and the folded antenna will automatically open again.

Nitinol can also be used for the early alignment and leveling of patients’
dentition. Due to the superelasticity and shape memory properties of the Nitinol
archwire and the lower stress-strain curve, the Nitinol archwire is currently
routinely included in the clinical practice. The arch wire of the orthodontic

Nickel-titanium push springs and tension springs are springs for
orthodontics. They are super-elastic with nickel-titanium, and are suitable for
orthodontic treatment to open up gaps between teeth and pull teeth in different

Due to the Russia-Ukraine conflict and the covid-19 pandemic, how will the international situation develop is highly uncertain. It is too difficult to assess its economic impact properly. However, we could see energy prices and commodity prices keep rising and supply chains are disrupted. Therefore, Nitinol prices are expected to rise in the future.
