Strong Disc Neodymium Iron Boron Magnet

• High remanence, high coercive force, high energy, etc
• High resistance to magnetic demagnetization
• Excellent cost to performance ratio
• Not suitable for application which exposed to high temperatures.
• Widely used in mini-motors, wind generators, meters, sensors, speakers, magnetic suspension system, magnetic transmission machine and other industrial applications.
• Very easy to corrosion in humid environments, so it is necessory to do the surface treatment according customers' requirements. We can offer the coatings, such as Zinc, Nickel, Nickel-copper-nickel, Silver, gold-plating, Epoxy coating, etc
