Send Inquiry

NdFeB magnets are mainly made of Neodymium, Iron and Boron with excellent magnetic property, produced by powder metallurgical method with chemical composition of Nd2Fe14B, possessing high energy ranging from 26MGOe to 50 MGOe, wonderful coercive force and high resistance to demagnetization. Accordingly, The NdFeB magnets provide the highest capacity.

NdFeB magnets can be used as an ideal magnet in mini-motor, sensors, audio speaker or auto parts, etc. The surface treatment methods include Zine, Nickel, Tin, Silver, Phosphor and Spray Epoxy Resin, etc. As the kind of permanent magnet, these are one of the most-used types of rare-earth magnet for wide and custom applications in industrial markets.

Because NdFeB magnets possess greater strength among much more smaller and lighter magnets, they have been applied to different fields, including motors in cordless tools, hard disk drives and magnetic fasteners.
