Sintered Neodym Magnet Outsanding product:

1)high performance:N*2,N*8M,*8SH,*2UH,*8EH,*3AH

2)high working temperature:the AH series with *0 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.*7 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 ***0 hours

5) low weight loss

PCT:**0c ,humidity **0%,vapor pressure 2.7 bar.*0 days,average low weight loss less than 2 mg/cm2

Sintered Neodym Magnete 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
