Sintered Neodymium Iron Boron magnet (Ndfeb magnets,magnet ring,magnet tiles,block magnets, magnet cylinder,ball magnets, rare earth magnet, permanent magnets)
The Sintered NdFeB magnet has the high remanence , high coercive force, high energy product and high performance,cost ratio, also have the high temperature model to suit for high temperature condition. It is easily formed into various sizes, including tile magnet, magnetic cylinder, magnet block, sphere magnets, horseshoe magnets, can be single magnetization, two poles and multi-poles magnetization, are widely used in mini-motors, wind generators, meters, sensors, sound device, magnetic suspension system, magnetic transmission machine and iatrical apparatus and other applications. It is prone to corrosion in humid environments, usually need surface treatment according to customer's requirements to protect magnet. We can offer the coating included: Zinc, Nickel, Silver, Gold-plating, Passivation, Phosphor,rubber and Spray Epoxy Resin.
