Neodymium Magnet 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. NdFeB Data Sheet Samarium cobalt Magnet Samarium cobalt magnets (also know as SmCo magnet), a type of rare earth magnet, are made of an alloy of samarium and cobalt. Developed from the 1970's, they came as a revolutionary product, initially tripling the energy product of other materials available at the time. They are generally ranked similarly in strength to neodymium magnets, but have higher temperature ratings, higher coercivity and extremely resistant to demagnetization. They can typically be used up to 300 °C. They are brittle, and prone to cracking and chipping. They are available in two “series”, namely Series 1:5 and Series 2:17. SmCo Data Sheet
