MATERIAL

Permanent Neodymium Magnet Standard

Neodymium Magnet is divided into sintered neodymium magnet and bonded neodymium magnet, both of which have excellent magnetic properties and are widely used in permanent magnetic Motors, loudspeakers, magnetic separators, wind power, and new energy electric vehicles. Features: Strong magnetic force, easy oxidation.
