Ring Sintring NdFeB
Applications of ring-typed sintered NdFeb: magnetic devices for reducing smokes and saving oil, tunable filters, oscillators, isolators, circulators, magnetic latching relay, watt-hour meters, water meters, counters, reed switch and sensors and instrumental meters.
permanent neodymium magnet sorption, ads, books managements, teaching tools and other office automation, permanent magnetic instrumental meters, electronic industry, automotive industry, nuclear magnetic resonance, magnetic suspension system, transmission gears and magneto therapy equipments.
brief introduction:
1.Chemical composition: NdFeB
2.High magnetic-rheological, High coercive force, high MGOe, high performance and low price
3.This material has coatings and good in anticorrosion
4.It is easy to be processed into all size or even the smallest specfication and to be widely used

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.
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 magnetsbrief introduction:

Ring NdFeB Magnet Out sanding 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
