Rare earth permanent magnet materials are used in various micro motors in computer, automobile, instruments, meters, household appliances and other industries, as well as nuclear magnetic resonance equipment, electrical parts, magnetic separation equipment, magnetic machinery, magnetic therapy equipment and other components that need to generate strong gap magnetic field. The development of rare earth metals in high-end military manufacturing, new energy, new materials and other industries cannot be separated from the application of some key materials. Recently, Tesla "got rid of" the rare earth plan, and A number of A-share listed companies in the rare earth industry have said that the demand for rare earth will not change much, and the future development of the rare earth industry is full of hope.

Middle stream of rare earth permanent magnet industry in China: Distribution of enterprises

Data show that in 2022, there are 1,964 rare-earth permanent magnet enterprises registered in China. The number of rare-earth permanent magnet enterprises in Jiangsu Province (417) ranks the first in China, followed by Inner Mongolia Autonomous Region (216). Zhejiang Province, Guangdong Province and Jiangxi Province all have more than 100 rare-earth permanent magnet enterprises, ranking the third, fourth and fifth respectively.

The downstream of China's rare earth permanent magnet industry: Consumption structure

Data show that rare earth used as permanent magnet materials has the highest proportion in our country, up to 46%, followed by metallurgical machinery (13%). Permanent magnet materials were the most used in manufacturing traditional automobiles and wind power, both accounting for 29 percent. As the dual-carbon target and "clean energy" and other environmental protection concepts are supported by national policies, new energy vehicles, wind power and rare earth permanent magnet motors with the concept of carbon emission reduction will be fully developed in the future, and it is expected that the demand for high-performance ndfeb magnetic materials will be greatly increased.

China's rare earth permanent magnet industry downstream: wind power industry

Wind power generation is one of the important applications of NdFeb magnets (rare earth permanent magnets). The use of rare earth permanent magnets as components of wind turbines has many advantages. The permanent magnet used by wind turbine is usually NdFeb permanent magnet, namely the third generation permanent magnet. In the design of permanent magnet motor, the choice of advanced NdFeb to obtain high air gap magnetic density, so that its work efficiency is higher. Ndfeb permanent magnet has temperature stability and can withstand the test of high temperature and cold. The magnetic properties of Ndfeb magnets are consistent. Large permanent magnet wind turbines usually use thousands of neodymium magnets. Each pole of the rotor contains a number of magnets. The consistency of rotor pole requires the consistency of magnet, including the difference of size and the consistency of magnetic properties. The so-called consistency of magnetic properties includes that the variation of magnetic properties between different individuals should be small, and that the magnetic properties of individual magnets should be uniform.

Development trend analysis of rare earth permanent magnet industry in China

The demand for new energy vehicles is growing, and the demand for high-performance materials is rising

In the past decade, the downstream application scenarios of rare earth permanent magnet have been gradually extensive. Traditional demands such as automobiles, wind power, frequency conversion air conditioning and so on have been growing steadily, and there is also huge potential in emerging demands. As environmental protection concepts such as dual-carbon target and "clean energy" are supported by national policies, the demand for new energy vehicles based on the concept of carbon emission reduction will increase in the future, and the technology of new energy vehicles will continue to improve, and the market demand will be released. As an important raw material for the manufacturing of new energy vehicle batteries, rare earth permanent magnet materials are expected to significantly increase the demand for high-performance ndfeb magnetic materials.
