Block NdFeB Magnet

NdFeB magnet also known as neodymium-iron-boron,neo,neodymium magnet, neodym magnet,rare earth magnet,neodyme memagnet,neodymium rare earth magnet, it is one of permanent magnet. The merit of ndfeb is that it has excellent performance and cost ratil and good machinery feature of easy machining, Its demerits lie in its low curie temperature ,bad thermal feature, easy erosion, which should be improved to achieve desired requirement with the adjustment of chemical composition and surface treatment. Such as passivation,Zinc,nickel,double nickel,Nickel+Copper+Nickel,black nickel,epoxy,copper,gold,silver,tin,parylene and spray-paint etc. Neodymium magnets have replaced Alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets. Such as speakers and headphones,magnetic receiver,magnteic separator,magnetic lifter,magnetic filter,magnetic chuck,magnetic hook,magnetic cup,magnetic pot,magnetic resonance imaging,magnetic sensors,magnetic coupling,magnetic bearing,magnetic brake and clutch,gearless motor,servo motor,spindle motor,steeper motor,compressor motor,synchronous motor,Actuators,magnetic jewelry and toys etc . Advantage of our company: 1. products manufactured according to ISO9001 quality system and tested according to GB/T 2828 (ISO 2859) or GB/T 2829-87 , we ensure the quality of our offered magnet.2.

Advanced techniques: Utilizes new Sintered NdFeB magnet techniques and equipment such as strip casting, HDDR technology in our factory to allow us to make high performance NdFeB over N52 possible5. The Excellent strength value: the highest(BH)max reaches up to 51 MGOe.6. The Extremely resistance to demagnetization with Hci,the intrinsic coercive force is over 33000 Oe.7. Insure the magnet 's consistencycould reach 5%.8. we could provide the minimum thicktolerance as +/-0.007MM or ID tolerance as +/-0.03MMand small unusual shape magnet been produce as customer's request.9. Also provide various shape of radial magnetic ring as customer's request.10. We will provide our customers the test report and BH cures and MSDS for each item magnets ,and also we can do the PCT (Hast)test, salt spray test report ,aging test report and provide the test report and so on according to our customer’s request.
