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.

Sintered Neodymium Magnet Outsanding 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
Sintered Neodymium Magnet applications:
Loudspeakers, motor assemblies, windmill, Home appliance, acousics,
communication equipment, toy, car, servomotor, step motor, DC motor
and linear motor, mircrophones
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
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
