Sintered Neodymium Iron Boron(NdFeB) magnets are made from different kinds of rare earth materials, such as ND, Dy, Fe, Al, Nb, Ga, Mo, Co and few other metals and they are the third generation rare earth permanent magnets that is the strongest magnets in the world and they feature high remanence, high corrective force and high energy products and they are more than 10 times stronger than ferrite(ceramic) magnets. They are very brittle so it is hard to machine them and the higher grades of NdFeB magnets are always more brittle than lower grades when they are machined in the cutting, drilling, milling and even coating process.
They are very easy to rust because they are the combination of many kinds of rare earth materials so we usually need do coating/plating on them before shipment. The ordinary coatings include Nickel(Ni-Cu-Ni), Black nickel, Zinc(Trivalent), Epoxy, Tin, Gold, Silver & Parylene etc. The ordinary grades of NdFeB magnets have N35, N38 to N52, N35M, N28M to N48M, N33H to N46H, N33SH to N44SH, N30UH to N35UH and N30EH to N35EH and their BHmax is 52MGOe that is the highest grade We can make now. Their highest working temperature is 200 ° C. They almost can be any size and shape, such as block, disc, ring, segment, cylinder and any special shapes. They have wide applications such as wind generators, DC motors, air conditioners, servo motors, PM motors, linear motors, VCM, medical apparatus, electronic components, toys, hand crafts and other magnetic holding and seperating products.
