Rare earth Disc/Round Ndfeb Magnet D12x3mm Nickel Plated for Various Motors
Brief Introduciton of NdFeB Magnet
Neodymium magnet (Nd-Fe-B) is one of the highest property and strongest permanent magnet by now, are made through powder metallurgy manufacturing techniques.
They are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc.
Neodymium magnet is regarded as “Magnet King” due to its recorded high remanence, coercive force and maximum energy product. With Neodymium magnet rapid development, many high-tech products were developed. Especially its application in motors makes products miniaturization and micromation.
At the same time, because of its high remanence, coercive force and maximum energy product, this type magnet is widely used in servo motor, flat brushless motor, step motor, IT products, Nuclear Magnetic Resonance, speaker and other products.
NdFeB magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.
Everbeen Magnet is specialized in various permanent magnets, and has been involved in production, technical research and sales in magnet field for more than 15 years. We mainly produce sintered Neodymium magnet of various grades, We can customize the magnets according to clients’ design and requests.
Everbeen Magnet has won the trust and good reputation from domestic and foreign famous enterprises under the commercial idea of “Profession, High Efficient, Honesty and Respect”. Over 70% of our magnets are sold to Southeast Asia, European and American area.

★ Operation Instructions:
NdFeB magnets have the character of hardness and brittleness. After the magnetization, it’s magnetic attraction is big as 60times as the its own weight. So the Neodymium magnet must be picked up carefully and gently during assemble process and kept away from iron ware to avoid mutually attracting, causing chips and cracks or other damage to the magnet. For the bigger size, the personal safety and self-protection are more important. it’ll hurt operators in case that two strongly magnetized slices firmly attract unexpectedly. You can use machine equipments just like bolt or stick craft to assembly and fasten them.
