NdFeB, simply, is a magnet, and we usually see except that magnet, its excellent magnetic properties and are called "Magneto." NdFeB contains large amounts of rare earth elements neodymium, iron and boron, its characteristic hard and brittle. Since the surface easily oxidized corrosion NdFeB need for surface coating. Surface chemical passivation is one good solution. As an NdFeB rare earth permanent magnet material has a very high energy product and coercive force, while the advantages of high energy density makes NdFeB been widely used in modern industrial and electronic technology, so that the instrument miniaturized instrumentation, electro-acoustic motors, magnetic separation equipment such as magnetic, lightweight, thin as possible. NdFeB advantage is cost-effective, with good mechanical properties; downside is that the low point of the Curie temperature, the temperature characteristic is poor, and easy-to-powder corrosion, so it must be improved by adjusting the chemical composition and surface treatment method adopted in order to achieve practical application. Ferrite magnetic tile

NdFeB magnetic tile mainly used in permanent magnet motor, the motor and electromagnetic sources produce different magnetic potential through an exciting coil, a permanent magnet motor is a permanent magnet to generate a constant magnetic potential source. Tile in place of permanent magnet electric field has many advantages, make simple motor structure, easy maintenance, light weight, small size, reliable, use less copper, low copper consumption, energy consumption and so on.
