Knowledge of sintered NdFeB magnet:
NdFeBmagnet is a kind of strong permanent magnet. Its lifetime can be 30 years when the working temperature is reasonable.
The most special feature is that its volume is small, but the pull force is very strong.
It can be used almost everwhere in our life, such as industrial , moto, speaker, arts and so on.

NdFeB magnet have the characteristics of:

Extreme strong Br residual induction
Very high energy product
Excellent demagnetization resistance capacibility
Coating is needed for NdFeB Magnet which is not suitable for high temperature working condition.
High Coercive Force
Very hight energy products
Low corrosion resistance (when uncoated)
Low mechanical strength – Brittle

Strongest magnetic power
Hight coercive force
Brittle & Hard
Good temperature stability
High resistance to demagnetization
Excellent performance and cost ratio
