Neodymium-Iron-Boron(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..

Magnets made from NdFeB ( Neodymium Iron Boron) are the most powerful permanent magnetic materials commercially available,possesses high energy ranging from 8 MGOe to 50MGOe and wonderful coercive force. As the third generation of Rare Earth permanent magnet, NdFeB products are less brittle than SmCo, Nd-Fe-B magnet is widely used in motor, instrument, aviation and the high-tech field.

Neodymium magnets are highly susceptible to corrosion. We offer a variety of coating and plating options to prevent corrosion and mechanical damage, such as Metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel,Gold, Organic Epoxy, Nickel+Epoxy coating.
