The NdFeB material has more advanced properties and multi-polar magnetization, which can make the same size motor generates larger torque or the same powder motor owns more ingenious volume.
So it meets the development demands of the " small, light and thin design" of the motor industry. with these properties, the NdFeB magnets are widely being used in modern advanced industry and high-technology products.
The
NdFeb is being widely used in aviation, spaceflight, electron, mechanism, meter and medical treatment field, etc.
Strong Sintered Neodymium Magnet
mainly comprised of neodymium ,iron and boron,is the third generation of the rare-earth permanent magnets,
Sintered Ndfeb is the strongest permanent magnets in the world up to date,It has excellent properties of high remanence,coercivity,and Max.energy product.

1)high performance:N52,N48M,48SH,42UH,38EH,33AH
2)high working temperature:the AH series with 40 k Oe super-high coervice force can replace
SmCo magnets successfully.
3)high consistency:the cpk of Br and Hcj are much higher than 1.67 the consisitency of surface magnetic field and magnetic flux can be controlled with +/-1%
4)High Anti-corrosion:the sale spray test and humid heat test of the high anti-corrosion coating could be more than 1000 hours
5) low weight loss
PCT:130c ,humidity 100%,vapor pressure 2.7 bar.20 days,average low weight loss less than 2 mg/cm2
Pros: Very strong hold when contacting another
magnet or plain iron, very difficult to pull away (easy to slide however).
Pretty strong hold between two of these even with a couple of mm in between.
Cons: Would like thicker (and more powerful) versions. Sure u can stack these together but sometimes it's not the same thing.
Other Thoughts: Good for attaching thick stacks of paper to refrigerators etc or pinching together papers or textiles.
Bottomline: This is the one if you need strong cost-effective
magnets
