Block 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
Block 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
