The brief introduction of Bonded Nd-Fe-B and Sintered ferrite

　　According to the production process, it can be divided into the following three types.

　　Bonded Nd-Fe-B: bonded NdFeB magnets are composite type neodymium iron boron permanent magnets that mix neodymium iron boron powder and resin, plastic or metal with low melting point binder uniformly, then with methods of compression, extrusion or injection molding. Product can be formed one time, without two processing, which can be directly made into various complex shapes.

　　All directions of bonded NdFeB magnets are magnetic, which can be processed into neodymium iron boron compression mold and injection mold with high precision, excellent magnetic properties, good corrosion resistance, high temperature stability.

　　Sintered ferrite's main raw material includes BaFe12O19 and SrFe12O19, on the basis of magnetic crystal orientation, and it can be divided into different isotropic and anisotropic magnet. Because of its low price and moderate magnetic energy is widely used as a magnet. Ferrite magnets are made ​​of ceramic technology, the texture is relatively hard, also is brittle materials, ferrite magnets have good temperature resistance and low prices, has become more extensive application of permanent magnets.
