Ndfeb Magnet

Neodymium-Iron-Boron(NdFeB) magnets are recently developed magnetic materials in1980's, with magnetic characteristics far exceeding those of the Alnico and Ceramic/Ferrite types. They are alloys of the Rare Earth group of element-neodymium. The composition is Nd2Fe14B.
Offering the highest energy products ever available in production permanent magnet materials, NdFeB has been widely used in high performance stepper, DC, servo, and linear motors, actuators, loudspeakers, headphones, instrumentation, switches, relays, magnetic imaging for medical and geophysical applications, holding systems, magnetic bearings, magnetic couplings, hard disk drives, etc.
