As the latest result of the development of rare earth permanent magnet materials, it is known as "magneto king" because of its excellent magnetic properties. Neodymium iron boron magnetic material is an alloy of neodymium and iron oxide, also known as magnetic steel. It is an important functional material in industrial, military and civil fields because of its high magnetic energy product, coercivity and high energy density. Whether electrical energy is converted into mechanical energy, electrical energy into sound energy, or mechanical energy into electrical energy, NdFeB plays an important role.

As the third generation of rare earth permanent magnet material, NdFeB has strong magnetism, small volume and light weight. It is a cost-effective magnet at present. It can well meet the needs of light and small downstream products, energy saving and consumption reduction, making the terminal products more comfortable, convenient, energy-saving and efficient, and has a very broad application space.
