The periodicity of the high-performance NdFeB permanent magnet material industry fluctuates with the fluctuation of the downstream industry. Although the development cycle of the downstream industry is not the same, it generally fluctuates with the fluctuation of the economic cycle. As the downstream new energy and energy conservation and environmental protection sectors belong to the industries encouraged and supported by my country's industrial policies, they will maintain rapid development for a long time in the future. Therefore, the high-performance NdFeB permanent magnet material industry is not significantly affected by economic cycle fluctuations.
