Sintered neodymium-iron-boron magnet (also known as Neodymium, Neodym, NdFeB, or Neo magnet) is the most widely used type of rare-earth magnet, which is made from an alloy of neodymium, iron, and boron. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnet is the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 30 MGOe to 52 MGOe, very high remanence and coercivity. It has replaced the traditional magnet materials in the many applications in modern products, such as electric motors, generators, hard disk drives, MRI, speakers, and etc. Segment Rare Earth Magnets for Brushless Motors UK Customer.
• Neodymium magnets are hard and brittle and may chip or break if dropped.
• disc Neodymium magnets are magnetized through the thickness.
• Uncoated neodymium magnets may corrode in humid conditions
• Operating temperatures vary among material grades. For a comparison of neodymium material grades.
• Neodymium magnets are often assembled into products using strong adhesives, Make sure that all contact surfaces are clean and dry prior to bonding.
• Please use caution when handling magnetized neodymium magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that fingers in their path could prove painful.
