Cylindrical Magnet

The rare earth permanent magnet material NdFeB has extremely high magnetic energy product, coercive force and energy density, as well as good mechanical properties. It is the strongest permanent magnet material among modern magnetic materials, so it has been widely used in modern industry and electronic technology. 

Aodmagnet can provide various surface treatments such as chemical treatment, coating treatment, metal plating, etc. according to your requirements. By adding trace elements and using a special aging process, the product has high coercive force, high magnetic energy product, low temperature coefficient, and low weight loss properties.

Electroplating process: zinc plating, nickel plating, gold plating, epoxy resin.

NdFeB magnets are widely used in machinery, audio-visual equipment, communications, medical equipment, automation equipment, aerospace, automobiles, elevator motors, wind turbines, CNC machine tools, servo motors, new energy vehicles, DC motors, sensors, speakers, compression equipment and other fields. Automotive, electronics, home and office products, signage, packaging and gift boxes, advertising production.

NdFeB magnets are mostly non-standard parts. The shape and size of magnets are generally processed according to customer needs, such as round magnets, square magnets, ring magnets, cylindrical magnets, arc magnets, irregular shape magnets, etc. Please feel free to contact us for a customized service that suits your needs.
