Coating: None or Customized Detail Features of product: 1) Low cost 2) High corrosion resistance 3) High working temperature 4) Best choice for industrial application Applications: Motors, Meters, Speakers, Sensors, Medical Machine products, Magnetic Sport products, etc The elements of Ferrite Magnet are ferric oxide/barium, strontium, Ferrite magnet has high coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets. The biggest advantage of such magnet is their low cost. We can produce various sizes of block-magnets, Disc-magnet, ring-magnet, segment-magnets, cut-magnets and other normal magnets, They are widely used in motor, speaker, electronic component, electric appliances, toy, stationery and health article.
