NdFeB magnets
Neodymium magnets can be called NdFeB magnets, which is a general term for strong magnets. The chemical formula is Nd2Fe14B, and it is one of the artificial permanent magnet materials with the strongest magnetic force so far. The material grade of NdFeB magnets is N35-N52, which can be processed into different shapes according to specific requirements, such as round, square, punching, magnetic tile, magnetic rod, convex or trapezoidal, etc.

Production process of sintered NdFeB magnets
Sintered NdFeB magnets are anisotropic magnets produced by powder sintering. Generally, only blanks can be produced by sintering, and magnets of various shapes need to be mechanically processed (such as wire cutting, slicing, grinding, etc.). Sintered NdFeB is a hard and brittle material that is difficult to process, so it has large processing loss, high cost, poor dimensional accuracy, poor corrosion resistance, and the surface needs electroplating, but the advantage is high performance, which has reached more than 50M at present.
