Neodymium Iron Boron Magnets: Neodymium Iron Boron magnets are currently the highest-performing magnets commercially available, known as the "magnet king," with extremely high magnetic properties. Their maximum energy product (BHmax) is more than 10 times that of ferrite. Their mechanical processing properties are also very good. The working temperature can reach up to 200 degrees Celsius. Moreover, they are hard and have stable performance, making them very cost-effective. Therefore, their applications are extremely wide. However, due to their strong chemical activity, they must be coated with a surface treatment.

      Nd2Fe14B-based permanent magnet materials are based on intermetallic compounds. Compared to casting Al-Ni-Co permanent magnet materials and ferrite permanent magnet materials, Nd2Fe14B has extremely high magnetic energy product and coercivity, capable of attracting a weight equivalent to 640 times its own weight.
