Sintered NdFeB magnet has the high remanence, high coercive force, high energy product and high performance/cost ratio. It is easily formed into various sizes, and widely used in mini-motors, meters, sensors, sound device, magnetic suspension system, magnetic transmission machine and iatrical apparatus and other applications. It is prone to corrosion in humid environments, so it usually needs surface treatment according to customers' requirements. The coatings we can offer include: nickel, zinc, silver, gold, passivation, phosphor and epoxy resin.
