Sintered NdFeB is the most powerful and advanced permanent magnet today .Sintered NdFeB has the high remanence, high coercive force and high energy. It has very high performance and high cost ration.
It can be easily formed into various sizes and different shapes, which are segment, disk, ring, block, multi-pole radial ring, special and so on.
The sintered NdFeB magnets have some limitations due to their poor corrosion resistance. In high-humidity, high-temperature, high-PH applications, protective coating is necessary for the sintered NdFeB magnets. Available coating includes plating, electrophoresis, parylene, and combinations of these coatings, as blow surface protection.
