How is neodymium iron boron manufactured？

Neodymium iron boron is a new high-performance magnetic material with excellent properties such as strong magnetism, high magnetic energy product, and good chemical stability. It is widely used in fields such as electric motors, automobiles, aerospace, and is known as the magnetic king of the 21st century.
Neodymium iron boron (NdFeB) is a new type of permanent magnet material, which is one of the important materials in modern electronics, communication, automotive, motor and other fields due to its stable performance and high magnetic energy product. So, how was it made?
Firstly, the raw materials for producing neodymium iron boron are elements such as neodymium, iron, and boron. These raw materials are mixed in a certain proportion and made into alloys, which are heated and cooled in a vacuum furnace to obtain neodymium iron boron billets.
Next, cut the neodymium iron boron blank into the required shape and size, and then undergo grinding, polishing, and other processes to make its surface smooth and size accurate. At the same time, composite deposition or solution deposition techniques are used to coat the surface of neodymium iron boron to improve its oxidation resistance and wear performance.
Finally, the neodymium iron boron is magnetized to have a certain direction of magnetism. This process usually needs to be completed in a strong magnetic field, usually using batch automatic magnetization equipment or manual operation to magnetize a large number of samples.
It can be seen that manufacturing neodymium iron boron requires rigorous process flow and technology, as well as high-precision equipment and professional workers. But in the long run, manufacturing neodymium iron boron has played a positive role in promoting industrial structure upgrading and technological progress, and has also brought more practical benefits and convenience to people's production and life.
