Neodymium iron permanent magnet materials came out in the early 1980s, and are now widely used in various fields such as information industry, national defense industry, automobile industry, wind power generation, household appliances, instruments and meters, medical equipment and magnetic instruments; The main component of the magnet is Nd2Fe14B, which has extremely high magnetic properties. Its maximum magnetic energy product (BH) max is more than 10 times higher than that of ferrite, and the maximum working temperature can reach 250C; The mechanical properties are also quite good, which can be suitable for different processing methods such as grinding, wire cutting and drilling; Due to poor corrosion resistance, different coating treatments must be carried out on the surface according to different requirements. (such as plating in, Ni, Au, Epoxy, etc.)
Main characteristics: NdFeB ferrite is made by powder metallurgy, and its chemical composition is Nd2Pe14B, which is the magnetic material with the highest magnetic properties at present; Its advantages are high demagnetization resistance and high performance-price ratio. Its disadvantages are strong temperature dependence and weak corrosion resistance. However, after proper coating or electroplating, plus different products with different coercivity in different use environments, neodymium iron boron can basically meet the use requirements of different customers.
