Surface treatments
The corrosion resistance of NdFeB (Neodymium) magnets is considered poor. Surface coating or plating is therefore highly recommended for NdFeB (Neodymium) magnets. All kinds of surface coating are available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn, Chrome and etc.
Application
Widely used in automobiles, mobile phones, digital cameras, jewelry, clothing, all kinds of hardware accessories, electrical, laser heads, toys, gifts, speakers, packing, leather goods, medical equipment and adverying, Switchboard, voice coil motors (VCM's) in hard disk drives, high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors, loudspeakers etc.
Magnet ShapeDisc, Ring, Cylinder, Block, Arc, Ball, Trapezoid, Countersunk, Irregual Shapes and More.
