NdFeB sintered magnet have not only higher Maximum Energy product, (BH)max and strength but also a lower density than Sm-Co sintered magnet.
In spite of their superior properties, the temperature stability of NdFeB is not as good as Sm-Co magnet.

Magnetic performance of NdFeB magnet is restricted by working temperature the maximum working temperature depends on a corvaility and magnet shape.
We can offer technical service for proper magnet design, Compared of Sm-Co magnet. The corrosion and oxidation resistance of NdFeB is relatively low.
A surface coating is usually applied on NdFeB magnets.

We have various surface coating techniques, Ni electro plating, Ni electro less plating , parylene coating and epoxy coating.
