What is Shape Memory Alloy Nitinol

Since the beginning of this year, people around the world have felt the pressure of rising prices. Not only the rise in oil prices but also different industries have seen soaring prices. According to the latest data, from August 2021 to the present, the inflation rate in the United States has risen for 6 consecutive months, and this data has soared from the previous 5.3% to 7.9% today. Inflation in the United States, the global Many countries have been affected.
According to experts' forecasts, the inflation rate in the United States may exceed 10% this year, which will face the danger of collapse, which has a great impact on global inflation, including Nitinol.

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 system.


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 directions.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.  

The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.  

Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.  

U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.  

The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."  

The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Nitinol are estimated to be influenced by international political situation changes.
