NdFeB, as a kind of rare-earth permanent magnetic material, consists of three elements: neodymium, iron and boron, and is known as the "king of modern permanent magnets" for its excellent magnetic properties and wide range of applications. So, what is the charm of NdFeB? In what fields does it play an important role?

NdFeB has the advantages of high remanent magnetic density, high coercivity and high magnetic energy product, and its magnetic properties far exceed those of traditional magnetic materials. In addition, NdFeB magnets are not only strong in magnetism, but also can pick up 1000 times of its own weight of iron, and the price is relatively cheap, which makes it has a very high application value in many fields.

The manufacturing process of NdFeB magnet mainly has three kinds of sintering process, bonding process and injection molding process. Sintering process produces NdFeB magnets with very high coercivity and maximum magnetic energy product, magnetic stability is very good; bonding process can realize one-piece molding, no need to cut the operation, convenient to provide a variety of shapes of permanent magnets; injection molding process through injection molding, compression molding and other ways of molding, with a short production cycle, low cost and other advantages.
