What is Shape Memory Alloy Nitinol
The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on 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
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

The Free Trade Agreement between India and the United Arab Emirates (UAE) has come into force on.
The UAE is the gateway to the Middle East, North Africa, Central Asia, and sub-Saharan Africa, said Subramaniam, a senior official at India's Ministry of Commerce and Industry. The agreement will help boost bilateral trade in goods from $60 billion a year now to $100 billion a year within five years.
On 18 February 2022, India and the United Arab Emirates signed the Comprehensive Economic Partnership Agreement. With the entry into force of the agreement, 90 percent of Indian goods and 65 percent of UAE goods will enjoy tariff-free market access.
Apart from its FTA with the UAE, India is also pursuing FTAs with Australia, the UK, Canada, Israel, the European Union, and the Gulf Cooperation Council.
Influenced by international situations, the supply and prices of many Nitinol are still very uncertain.
