Permanent magnet (Nd-Fe-B NdFe1B): according to the different production process is divided into the following three

(1), sintered neodymium iron boron (Sintered NdFeB) -- (sintered NdFeB magnets by jet milling after smelting and become, the coercivity values of magnetic is very high, and have a high energy, the maximum energy product (BHmax) is higher than the ferrite (Ferrite) more than 10 times. The mechanical properties of its own is also very good, can cut different shape and drilling. The highest working temperature can reach 200 degrees Celsius high performance products. Due to easy matter content it causes corrosion, so the surface coating layer must be according to the different requirements of different. (such as the deposition of Zn, Ni, Au, Epoxy etc.). Very hard and very brittle, high anti back magnetic, high cost / performance ratio, are not suitable for high temperature);

(2), bonded NdFeB (Bonded NdFeB) -- bonded NdFeB is neodymium iron boron powder and resin, plastic or low melting point metal binder mixing, composite type neodymium iron boron then made by compression, extrusion or injection molding method of permanent magnet. A product forming, without the need of two processing, can be directly made into various complex shapes. The direction of the bonded NdFeB are magnetic, can be processed into neodymium iron boron compression mold and injection mold. High precision, excellent magnetic properties, good corrosion resistance, good thermal stability.

(3), injection molding neodymium iron boron (Zhusu NdFeB) -- has a high accuracy, easy to produce thin walled ring anisotropic complex shape or thin magnet
