Fourth Generation Permanent Magnet SmFeN Development Trend

Market supply and demand Status and Development Trend Forecast Report of samarium iron-nitrogen Permanent magnet material (SmFeN) industry in China from 2024 to 2028

Samarium iron-nitrogen permanent magnet material (SmFeN) has broad application prospects. At present, the production and application of SMFEN are still in the initial stage in China

Sm2Fe17Nx or Sm2Fe17NxH are ternary or multimetallic intercompounds formed by the nitrization of Sm2Fe17. Samarium iron-nitrogen permanent magnet material (SmFeN) is a special treated rare earth permanent magnet material, the main components are samarium, iron and nitrogen. According to the different process, samarium iron-nitrogen permanent magnet materials are divided into sintered type and bonded type two categories, of which sintered samarium iron-nitrogen permanent magnet material production technology is difficult, is still in a state of research and development.

Samarium iron-nitrogen permanent magnet material is considered to be the fourth generation of rare earth permanent magnet material after NdFeb permanent magnet material, according to the "2024-2028 China samarium iron-nitrogen permanent magnet material (SmFeN) industry market supply and demand situation and development trend forecast report" released by the Industrial Research center, in the era of all things electric drive, The motor gradually develops in the direction of high-speed, efficient and energy-saving, and the market demand for high-performance permanent magnet materials is rapidly released. In 2023, the market demand for samarium iron-nitrogen permanent magnet materials in China will reach about 300,000 tons. However, as a new generation of permanent magnet materials, samarium iron-nitrogen permanent magnet material production has certain technical barriers, and its production and application are still in their infancy, and the market size is small.

Samarium oxide is the main raw material of samarium iron nitrogen rare earth permanent magnet material. Samarium (Sm) is a rare earth element, samarium is a silver-white metal of medium hardness, which exists in the form of samarium difficult to free in nature, usually co-existing with other rare earth elements in minerals. China is rich in rare earth resources, and samarium oxide reserves rank first in the world, reaching about 650,000 tons. China is a major producer of samarium oxide in the world, and the output of samarium oxide has remained at about 4000 tons in recent years. From this point of view, the raw material supply of samarium iron-nitrogen permanent magnet materials in China is sufficient.

Industry analysts said that samarium iron nitrogen permanent magnet material is a new generation of rare earth permanent magnet material, excellent magnetic properties, in the automotive, robotics, aerospace, industrial motors and other fields of application prospects. China is rich in rare earth resources, sufficient supply of samarium oxide, samarium iron nitrogen permanent magnet material raw material cost advantage is obvious, but limited by technology, the current production and application of samarium iron nitrogen permanent magnet material in our country is still in its infancy, the future market development potential is huge. High coercive force, strong corrosion ability, high cost performance, high saturation magnetization, high Curie temperature and other characteristics. Under high temperature and harsh environment, samarium iron nitrogen permanent magnet material can also maintain good performance, and has broad application prospects in new energy vehicles, robots, industrial motors, computers, consumer electronics, communications, medical treatment, aerospace and other fields.
