NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.
The advantage is high cost-effective, with good mechanical properties, easy cutting.
Also have high Br,high Hcj,high (BH)max,and high stability become the important material of the world.
The shortcoming is the low of the Curie temperature and the temperature characteristics, easy to rust, oxidation, Sintered NdFeB's surface is usually required for plating such as zinc, nickel, silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.

Nd-Fe-B permanent magnet with its excellent performance, abundant raw material and reasonable price is to be rapid development and wide application.
Also becoming increasingly popular across a wide range of novelty products for markets.
APPLICATION:
