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
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 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
