Compared with the traditional permanent magnetic materials, rare earth permanent magnetic materials are the magnetic materials with the best magnetic properties and comprehensive properties, and have become the key basic materials of modern industry. At present, the third generation of rare earth permanent magnet material NdFeB permanent magnetic material is the most widely used, fastest developing and best comprehensive performance magnetic material. Sintered NdFeB magnetic material is the largest production and widest application range of NdFeB permanent magnetic material. High performance rare earth permanent magnet materials are widely used in low-carbon economic fields such as energy-saving and environmental protection manufacturing industry. With the rapid development of emerging industries represented by new energy vehicles, wind power generation, energy-saving household appliances, robots and intelligent manufacturing, high-performance rare-earth permanent magnetic materials are developing rapidly Material demand is expected to usher in rapid growth. It is estimated that from 2019 to 2025, the global demand for NdFeB permanent magnet materials for new energy vehicles will reach 45016 tons, with an average annual compound growth rate of 18.34%; by 2024, the global demand for high-performance NdFeB brought by wind power installation will be 20552 tons, an increase of 21.52% compared with that in 2019, and the average annual compound growth rate will reach 3.98%; It is conservatively estimated that by 2025, the demand for NdFeB permanent magnet materials for frequency conversion energy-saving household appliances will not be less than 9418 tons, which is 63.4% higher than that in 2019, and the annual compound growth rate is 8.53%; by 2024, the corresponding NdFeB consumption of global industrial robot sales will reach 23325 tons, with an average annual compound growth rate of 17.25%. The total demand of high-performance NdFeB magnetic materials in the three application fields of new energy vehicles, wind power generation and energy-saving household appliances in 2025 will exceed the total demand of global high-performance NdFeB magnetic materials in 2018, and the market prospect is worth looking forward to. From the perspective of supply growth of rare earth permanent magnet materials, the growth rate of China's high-performance rare earth permanent magnet materials is far less than that of the industry as a whole. During the three years from 2014 to 2016, the annual compound growth rate of China's NdFeB magnetic materials was 10.08%, while the annual compound growth rate of high-performance NdFeB magnetic materials was only 2.06%. There are six barriers to enter the field of high-performance rare earth permanent magnet materials, such as technical and talent barriers, manufacturing barriers of non-standard products, capital barriers, customer stickiness barriers, quality certification barriers, patent barriers and so on, which make it difficult for latecomers to enter the field of providing increment. However, the advantageous enterprises in the industry that have already grasped a large number of long-term customer orders are more willing to maintain the current situation and actively expand rapidly As a result, the supply of high-performance rare earth permanent magnet materials is limited. This provides the development space for the growth of domestic dominant magnetic material enterprises and makes them benefit continuously.
