Rare earth permanent magnetic materials are also an important branch of magnetic materials. China has become the largest producer of rare earth NdFeB in the world. New energy vehicles, energy-saving household appliances, electric tools, industrial robots and other industries have provided important support for the development of the rare earth permanent magnet materials industry.
From 2015 to 2019, the output of rare earth permanent magnet materials in China generally increased year by year. In 2019, China's output of rare earth magnetic materials remained stable, with an output of nearly 180000 tons. Among them, the output of sintered NdFeB blank was 170000 tons, a year-on-year increase of 9. 7%; The output of bonded NdFeB was 7900 tons, a year-on-year increase of 5%; The output of samarium cobalt magnets was 2400 tons, a year-on-year increase of 4%.
