【 Ndfeb magnet how anti-corrosion 】 Ndfeb magnet is very simple by corrosion. As a result, most finished products for electroplating may coating. Practice to choose appearance treatment include: nickel plating, Nickel and copper nickel) , galvanized, aluminum plating, electrophoresis, etc. If working in a closed environment, also can choose the method of phosphide. Ndfeb magnet is now widely used, rapid development of magnet products. The wide use of ndfeb from creation to the present, but also more than 20 years of time. Because of its high magnetic function and easy workability, the price is not high, so using field expanded rapidly. Now, the commercialization of ndfeb magnetic energy product can reach 50 mgoe, 10 times that of ferrite. Ndfeb is powder metallurgy products, processing methods and samarium cobalt is similar. Now, summary of the highest working temperature at 180 degrees Celsius. If be bad environment use, general introduction is not beyond 140 degrees Celsius. Features: ndfeb magnet and usually is compared with the permanent magnetic materials such as ferrite, ndfeb magnet has a very excellent magnetic properties. The magnetic energy product is much higher than other types of magnets, but said & quot; A generation of king of magnetic & quot; 。 Ndfeb magnet high saturation magnetization Bs ( b = 16公斤) HA and magnetocrystalline anisotropy field ( 哈= 73 koe) , ndfeb magnet products are widely used in packaging, toys, gifts crafts, fitness magnetron cars, motors, micro-motor, computer, instrument, appearance, motorcycles, cameras, clocks and watches, audio, home appliances, office automation, magnets and various fields of daily life. Because of the high of ndfeb magnetic function, on many occasions, be used to replace other magnetic materials, to reduce the volume of products. If use ferrite magnets, mobile scale now, I'm afraid to not less than half a piece of brick. Strong magnets, magnets, magnet, magnet, ndfeb magnet, rare earth permanent magnets
