ndfeb magnets

ndfeb magnetsmainly comprised of neodymium ,iron and boron,is the third generation of the rare-earth permanent magnets,Sintered Ndfeb is the strongest permanent magnets in the world up to date,It has excellent properties of high remanence,coercivity,and Max.energy product. ndfeb magnetsgrade: N35,N38,N40,N42,N45,N48,N50,N52(Max.operational temperature:80c) N33SH,N35SH,N38SH,N40SH,N42SH(Max.operational temperature:150c) N28UH,N30UH,N33UH,N35UH,N38UH(Max.operational temperature:up to 180c) N28EH,N30EH,N33EH,N35EH(Max.operational temperature:up to 200c) N30AH,N33AH,N35AH(Max.operational temperature:up to 230c) ndfeb magnetsOutsanding 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 ndfeb magnetsapplications: 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 you are welcome to enquiry on oursintered ndfeb magnets
