Star gen ndfeb magnetic industry manufacturers for you to answer why ndfeb magnet easily corroded?

Ndfeb factory just produce and processed products we call 'black', not by the electroplating of ndfeb magnet is very easy to corrode. For this reason, most finished products to the plating or coating. Regular use of surface treatment include: nickel plating ( Nickel and copper nickel) , galvanized, aluminum, electrophoresis, etc. If the work in a closed environment, also can adopt the way of phosphating. Ndfeb magnet is widely used at present, fast-growing magnet products. Ndfeb magnet from invention to now widely used, but also more than 20 years of time. Ndfeb manufacturers of magnets with high magnetic and workability, the price is not high, so the application area to expand rapidly. At present, the commercialization of ndfeb magnetic energy product can reach 50 mgoe, 10 times that of ferrite. Ndfeb is powder metallurgy products, processing way like samarium cobalt. At present, the summary of the highest working temperature at 220 ℃ or so, if it is a bad environment, general recommendation does not exceed 140 ℃. Ndfeb magnet characteristics: compared with the usually magnet or ferrite permanent magnet, ndfeb magnets have excellent magnetic properties, the magnetic energy product is much higher than other kind of magnet, can be called 'magnetic king'. Ndfeb magnet high saturation magnetization and magnetocrystalline anisotropy field, ndfeb magnet products are widely used in packaging, toys, gifts crafts, fitness magnetron cars, motors, micro-motor, computer, instruments, meters, motorcycles, cameras, watches, audio, home appliances, office automation, magnets and various fields of daily life. Ndfeb manufacturers of ndfeb magnets with high magnetic, on many occasions, is used to replace other magnetic materials, used to reduce the volume of products. If use ferrite magnets, mobile phone size now, I'm afraid not less than half a piece of brick.
