Specifications
Rare-earth Permanent magnet Nd-Fe-B is developed in the 1980?s with excellent magnetic characteristics in terms of high energy product, high coercive force etc. It is the most strong and powerful magnetic material up to now and regarded as the King of Magnet. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B is under a very fast development and wide application. It is getting to replace the traditional magnet of Ferrite, Al-Ni-Co and Sm-co in many field such as electro-accoustic device ,electrical motor, instrument and meter, auto industry, petro-chemical industry and magnetic health-care product. The basic and typical shape of the magnet used are disc, ring, tile and block (square). The surface is usually treated with Zinc, Nickel or epoxy resin coating
