Neodymium magnets are actually composed of neodymium, iron and
boron (they are also referred to as NIB or NdFeB magnets). The powdered
mixture is pressed under great pressure into molds. The material is then
sintered (heated under a vacuum), cooled, and then ground or sliced into the
desired shape. Coatings are then applied if required. Finally, the blank magnets
are magnetized by exposing them to a very powerful magnetic field in excess
of 30 KOe.
Advantages of Sintered Magnet:
1.The NdFeB magnet has high remanence, high coercive force, high energy
product and high ratio between performance value and product cost.
2.It can be easily formed into various sizes.Various shapes on offer: block,
round, ring, arc-even highly complex forms. Virtually any shape of neodymium
3.Smaller size and lighter weight in designing devices
4.High energy range from 30MGOe to 53MGOe with wonderful coercive force
