Neodymium magnets are currently found to be the most commercially available magnets. They are called Magneto. They have extremely high magnetic properties and their maximum energy product (BHmax) is more than 10 times higher than that of ferrite. Its own machining performance is also quite good. The operating temperature can reach up to 200 degrees Celsius. Moreover, its hard texture, stable performance, and good cost performance, so its application is extremely wide. But because of its strong chemical activity, it must be coated on the surface. (Such as Zn, Ni, electrophoresis, passivation, etc.).
Nowadays, neodymium magnets are rapidly developing and widely used. In many fields, it is possible to replace traditional pure iron magnets, alnico and samarium-cobalt magnets such as electric motors, instruments and meters, automobile industry, petrochemical industry and magnetic healthcare products. Can produce various shapes: such as disk magnets, ring magnets, rectangular magnets, arc magnets and other shapes of magnets.
