Custom different size of NdFeB magnet Ring

NdFeB permanent magnet materies came out in 1980,  Are widely  used in motor,speaker,toys and electron etc. It's composed of Neodymium,Ferrite,Boron and other trace metals.

Have ultra high magnet performance, maximum magnetic energy product (Bhmax) 10times of higher than Ferrite.have better mechnical performance,can be cut to different shapes and drilling. Its maximum work temperature reach up to 200℃.Due to its element include easy corrosion component , be demanded to different surface coating treatment according to using requirements.( such as Zincification,Nickel Plating,Au Plating, Epoxy Plating etc.) 

NdFeB is a alloy magnet composed of Neodymium,Fe,Boror and other trace metal elements. Is the strongest magnet rare earth magnet as far to found. Have very high magnetic energy product ( 8MGOe-55MGOe) and better Coercivity.its manufacturing process is mature, have strict quality assurance,perfect technical service and good performance cost ratio.

We manufacturing and sale top quolity of NdFeB permanent magnet,include the largest size of NdFeB magnet ring in the world !!!
