Development Trend of Rare Earth Permanent Magnetic Materials Industry

(1) Extensive application areas
Rare earth permanent magnet materials have been widely used in many fields such as electronic information, automobile industry, medical equipment, energy and transportation. At the same time, with the continuous advancement of technology, rare earth permanent magnet materials have also shown wide application prospects in many emerging fields. Especially under the general trend of low-carbon economy sweeping the world, countries all over the world pay attention to environmental protection and low-carbon emissions as key areas. China will achieve a 40%-50% reduction in carbon dioxide emissions per unit of GDP in 2020 compared to 2005. This has put forward new ideas for China in improving energy structure, developing renewable energy, increasing efficiency, energy saving and emission reduction, and advocating low-carbon life. The requirements also provide a broad market space for the development of low-carbon economic industries such as wind power generation, new energy vehicles, and energy-saving home appliances. In the future, rare earth permanent magnet materials will be widely used in wind power generation, new energy vehicles, energy-saving home appliances and other fields, and the application fields will be more extensive.

(2) NdFeB permanent magnet materials will replace other magnetic materials
The properties of NdFeB permanent magnet materials have comparative advantages. NdFeB permanent magnet materials have high intrinsic coercivity, magnetic energy product and remanence. Higher magnetic energy product is conducive to the miniaturization, light weight and thinning of instruments and meters. At the same time, the application of high-performance NdFeB permanent magnet materials in the fields of new energy and energy saving and environmental protection is based on its advantages of miniaturization, energy saving and environmental protection. Although the initial cost of high-performance NdFeB permanent magnet applications is relatively high, it has long-term energy saving value. More prominent, so the demand is more rigid. In addition, NdFeB permanent magnet materials do not contain cobalt, which is a strategic element, and are more cost-effective, have better mechanical and mechanical properties, and can be cut and drilled, and have a higher yield.

(3) Trend of extension to high-end applications
In recent years, driven by the rapid development of new energy and energy conservation and environmental protection, the industry of high-performance rare earth permanent magnet materials has grown rapidly. However, with the continuous extension of downstream application fields and the increasingly complex application environment of high-performance rare earth permanent magnet materials, the requirements for the degree of refinement of products have become increasingly strict, and the requirements for product surface treatment and other technologies have become higher and higher; at the same time, Under the pressure of the scarcity of rare earth materials on production costs, the future improvement of product quality, the reduction of rare earth materials, and the reduction of rare earth materials consumption rate will be the development direction of the industry’s technology. High-performance NdFeB permanent magnet material production enterprises mainly rely on the introduction and absorption of foreign technology to start and develop. Generally speaking, their innovation and R&D capabilities are relatively weak. In recent years, with the improvement of scientific research and production technology, the magnetic properties of high-performance rare earth permanent magnet materials produced in my country have approached or reached the international advanced level, gradually breaking the foreign technology monopoly and entering the high-end application field.
