About us: huge ring SUPER ndfeb magnet
MPCO was founded in 2008,as a professional manufacturer and exporter,we are specialized in designing and producing of rare earth magnet, especially for sintered and bonded NdFeB magnets. Currently we mass produce N52,50M,48H,45SH, 40UH, 38EH , 33AH and other grade of sintered NdFeB magnet.They are widely used in Automobile, Wind Power, Servo and so on. Our factory is located in Ningbo ,Where is the industrial bases of Ndfeb magnet.

This is a magnet with a greater magnetic characteristic than all existing magnets, and the principal components are neodymium, steel, and boron. A Neodymium magnet is one of the major rare-earth magnets, and it achieves a high level of magnetism even after miniaturization because its power is greater than other magnets, so it is suitable for downsizing applications. A Neodymium magnet has satisfactory mechanical strength, but is unsuitable for high temperature locations. Galvanizing is applied for anti-rust protection. It is suitable for small motors, sensors, and precision machines, etc.
