Product Name: Magnet Sintered NdFeB Coating: Various Shapes Shape: Block Application: Industrial Magnet Type: Permanent Composition: NdFeB Magnet Trademark: Yuxiang Transport Package: Neutral Paper Carton Packing Specification: ROHS, SGS, CE Origin: Fujian, China (Mainland) HS Code: 850511900 Product Description Magnet Sintered NdFeB1, These Sintered NdFeB magnets are particularly suitable for high volumn production of awide variety of shape and size ranges. Precise dimensional control is achieved in both processed and usually the component does not require futher machining.2, Injection moulded NdFeB does not normally require coating due to high corrosion resistance, however coating is recommended for compression moulded NdFeB3, Neodymium Iron Boron (NdFeB) magnets, asort of Rare Earth magnet material, has the high remanence, high coercive force, high Maximum energy and is easily formed into various sizes, shapes. So they have been widely used in commercially available fields....4, It can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 52MGOe, while the bonded form holds alower energy product of up to 10MGOe. Furthermore, the majority of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction.5, NdFeB Magents are prone to corrosion in humid environments, It usually needs surface treatment according to customer's requirements to protect magnet..For more detail info, please feel free to inquire us at any of your convenience...Ying JunSenior technical manager Yuxiang Magnetic Materials Ind.
