The production process:
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), cool,
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 magnet
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
