Chemical properties and the application of the rare earth magnets

　　Rare earth magnets grade up to N52, 50M, 48H, 45SH, 40UH and 38EH, the maximum working temperature is 200oC. The parameter of rare earth magnet includes size, performance grade, magnetizing direction, coating and quantity. Because such magnets are easily oxidized and rust, usually using nickel plated treatment.

　　Chemical properties of rare earth magnets are the magnet that is based on Nd2Fe14B intermetallic compounds. The magnet has high magnetic energy product and coercivity. At the same time, the advantages of high energy density of rare earth permanent magnets is widely used in modern industry and electronic technology, which make the miniaturization, lightweight and thin equipment possible.

　　Rare earth is mainly used in micro motor, permanent magnetic instrument, electronic industry, automobile industry, petrochemical, nuclear magnetic resonance device, sensor, audio equipment, magnetic suspension system, magnetic transmission mechanism and magnetic devices etc.. It is also widely used in computer, magnetic machinery, auto control, microwave communications, aerospace, medical equipment and other fields.
