Global Nitinol market trend 2022-2027 What is the Special Properties of Nitinol by Newsstrikevector

The roble had hit a record low after the West imposed sweeping sanctions on Russia for its aggression in Ukraine. Russia's president recently ordered exports of Russian gas to "unfriendly" countries to be settled in robles. The speaker of Russia's upper house of parliament said Moscow was prepared and could shift supplies to markets such as Asia if Europe refused to buy Russian energy.

European countries, which pay mostly in euros, say Russia has no right to reset contracts.  The G7 rejected Russia's demand and urged companies not to agree to pay in robles, saying most contracts stipulated payment in euros or dollars. Wholesale gas prices in Europe have risen further recently on concerns about potential supply disruptions.

The Kremlin spokesman said, "According to the March 31 deadline set by Russia's president, we are developing all payment methods to get a simple, understandable, and feasible system for relevant European and international buyers,"

The markets and prices of more commodities like the Nitinol would be affected because of the volatile international political situations.

What is Nitinol?

Nitinol is a shape memory alloy, which is a special alloy that can automatically restore its own plastic deformation to its original shape at a certain temperature. Its expansion rate is more than 20%, its fatigue life is up to 1*10 to the 7th power, its damping characteristics are 10 times higher than that of ordinary springs, and its corrosion resistance is better than the current best medical stainless steel, so it can meet various engineering and It is a very excellent functional material for medical application requirements.

In addition to its unique shape memory function, memory alloys also have excellent characteristics such as wear resistance, corrosion resistance, high damping and superelasticity.

Special properties of Nitinol

Shape memory: When the parent phase of a certain shape is cooled from above the Af temperature to below the Mf temperature to form martensite, the martensite is deformed at a temperature below Mf, and heated to below the Af temperature, accompanied by reversal. Phase transition, the material will automatically return to its shape in the parent phase. In fact, the shape memory effect is a thermally induced phase transformation process in Nitinol.

Superelasticity The so-called superelasticity refers to the phenomenon that the specimen produces a strain far greater than the elastic limit strain under the action of external force, and the strain can automatically recover when unloaded. That is, in the state of the parent phase, due to the action of external stress, the stress-induced martensitic transformation occurs, so that the alloy exhibits mechanical behavior different from ordinary materials. Its elastic limit is much larger than that of ordinary materials, and it no longer obeys Gram's Law. In contrast to shape memory properties, superelasticity has no thermal involvement. All in all, hyperelasticity means that the stress does not increase with the increase of strain within a certain deformation range, and hyperelasticity can be divided into linear hyperelasticity and nonlinear hyperelasticity. 

In the former stress-strain curve, the relationship between stress and strain is close to linear. Nonlinear superelasticity refers to the result of stress-induced martensitic transformation and its inverse transformation during loading and unloading in a certain temperature range above Af, so nonlinear hyperelasticity is also called transformation pseudoelasticity. The phase transformation pseudoelasticity of Nitinol can reach about 8%. The superelasticity of Nitinol can vary with the heat treatment conditions, and when the archwire is heated above 400ºC, the superelasticity begins to decrease.

Corrosion resistance: Studies have shown that the corrosion resistance of nickel-titanium wire is similar to that of stainless steel wire

Commodities such as crude oil, wheat, cotton, and nickel have rallied since Russia's "special military operations" began in late February. On the last trading day of this quarter, commodities were on track for their biggest gain since 1990. For this reason, it is expected that the price of the Nitinol will continue to increase.
