What is the difference between NdFeB and ferrite in magnetic materials?
Ferrite: high resistivity, wide range of work, can be used in high frequency state... But the residual magnetic induction intensity and maximum magnetic energy product are lowNeodymium iron boron: with "magnetic king" said, as the name suggests, the magnetic energy is high, the remaining magnetic induction intensity, maximum energy products are very impressive, coercive force is also high and low points.. But it is easy to oxidize, Curie temperature is low and the working range is not wide.
For example, stability: ferrite stability is very good, it is itself oxide, very stable, NdFeB is alloy, and its easy to oxidation. Coating protection must be done
For example, the price of NdFeB is very expensive, ferrite is very cheapFor example, temperature resistance: ferrite is very good, NdFeB ordinary only 80 degrees
There's a lot of difference in performanceFirst of all, magnetic energy is not a grade, and is at least 10 times an order of magnitudeSecond, there are many other different aspects
