Sintered NdFeB magnets are produced by powder metallurgical process, which are the highest energy products at present. They are widely used in the MRI, VCM, Motor, Separator, lifting, sensors and loudspeaker. Feller can produce Sintered NdFeB magnets over 50 tons per month, many high capability magnets, such as N48, N42M, N42H, N40SH, N30EH, are in mass production. N30U.
