Neodymium Magnet mainly comprised of neodymium, iron and boron, is the thirdgeneration of the rare-earth permanent magnets, Sintered NdFeB is the strongestpermanent magnets in the world up to date, It has excellent properties of highremanence, coercivity, and Max. Energy product.
Neodymium Magnet grade
N35, N38, N40, N42, N45, N48, N50, N52(Max. Operational temperature: 80c)
N35M, N38M, N40M, N42M, N45M, N48M(Max. Operational temperature: 100c)
N35H, N38H, N40H, N42H, N45H, N48H, (Max. Operational temperature: 120C)
N33SH, N35SH, N38SH, N40SH, N42SH(Max. Operational temperature: 150c)
N28UH, N30UH, N33UH, N35UH, N38UH(Max. Operational temperature: Up to180c)
N28EH, N30EH, N33EH, N35EH(Max. Operational temperature: Up to 200c)
N30AH, N33AH, N35AH(Max. Operational temperature: Up to 230c)
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 coerviceforce can replace SmCo magnets successfully.
3)high consistency: The cpk of Br and Hcj are much higher than 1.67 theconsisitency 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 highanti-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 weightloss 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 linearmotor, mircrophones
Pros: Very strong hold when contacting another magnet or plain iron, verydifficult to pull away (easy to slide however).
Pretty strong hold between two of these even with a couple of mm inbetween.
Cons: Would like thicker (and more powerful) versions. Sure u can stack thesetogether but sometimes it's not the same thing.
Other Thoughts: Good for attaching thick stacks of paper to refrigerators etcor pinching together papers or textiles.
Bottomline: This is the one if you need strong cost-effective magnets
