    This patent pioneered the "permanent magnet material–slurry spraying–stacking–three-stage heat treatment" technology, overcoming the technical challenges of achieving both "high coercivity" and "high resistivity" in neodymium-iron-boron magnets, meeting the high-temperature resistance and high-performance needs in its application areas. The family patents of this patent have already been granted in the US, EU, and Japan. 


    Products related to the patent have been evaluated as reaching an international leading level, with significant social benefits. The patented products have been widely applied in energy-saving air conditioners, new energy vehicle drive motors, and have successfully entered the humanoid robot market. Looking ahead, the company will continue to promote the application of neodymium-iron-boron permanent magnet products in emerging fields like humanoid robots and low-altitude flight, providing key technological support for the high-quality development of the permanent magnet materials industry.
