The following details the development of new nickel titanium alloy materials

Japan developed super elastic nickel titanium alloy made

On September 11, researchers at the National Institute of Materials Science in Japan developed a new process that can "transform" Nitinol into super elastic materials. According to a paper published in the new issue of the journal Nature, the material is as strong as steel, 20 times more ductile, can be stretched like rubber, and is expected to be used to create deformable wings. Although the previous nickelinol alloys have special properties, their characteristics are limited by temperature. The researchers designed a new process with a "three-step procedure", first stretching the alloy by more than 50% of deformation, heating it to 300 ° C, and then stretching it by 12%, and the final material can withstand pressures 18,000 times higher than normal atmospheric pressure, and maintain properties in a wide range of -80 ° C to 80 ° C, and its unique molecular arrangement structure makes it both deformable and not easy to break.

Jiaxing enterprise research and development of medical devices with nickel titanium shape memory alloy

In 2024, "Nickel-titanium shape memory alloy for Medical devices" developed by Jiaxing Zhejiang Maitong Zhizao Technology (Group) Co., Ltd. was identified as the first batch of new materials in China. The company is the only enterprise in China that can provide 4 ~ 6mm Nitinol nerve interventional thrombectomy stent tube and realize industrial application. Its material is used in minimally invasive surgery by cutting the material into a stent, compressing it, feeding it into a neurovascular tube, using superelasticity to embed the clot into the stent, and then pulling the clot out to achieve healing. The medical device field has extremely high requirements for new materials, and Maitong intelligent Manufacturing has achieved technological breakthroughs through independent research and development.

Medical high precision implantable grade nickel titanium tube research and development project

On February 28, Kangti Medical Technology (Suzhou) Co., Ltd. signed a contract with Southeast University of Medicine for the development and industrialization of high-precision implanted nickel titanium tubes. The project has the leading nickel titanium alloy solution technology at home and abroad, high scientific and technological content, strong radiation driving force, and good market prospects. With a total investment of 100 million yuan, the project has been officially put into production in April 2024, and the cumulative output value is expected to exceed 500 million yuan within 5 years, and plans to be listed on the science and technology innovation board. The landing of the project will drive and attract more high value implantable medical device enterprises to invest in Zhangpu, promote the development of high end medical device industrial clusters, and promote the strengthening of the industrial chain.

Nickel titanium alloy welding wire preparation method patent

On November 29, Jiangxi Blue Microelectronics Technology Co., Ltd. applied for a patent called "Nickel titanium alloy bonding wire preparation method." The patent number is cn119035070a and the application date is September 2024. The preparation method adopts a special preparation equipment, in which the top opening of the ultrasonic vibrating sieve cylinder at the top of the device is covered with a dispersion cover, the top of the dispersion cover is fixed in communication with the drain pipe, and the other end of the drain pipe is provided with a fine powder trapping structure. In the process of producing nitinos, the structure can actively trap the micro-powder produced by the raw powder vibrating screen and collect it uniformly inside.
