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
