Anticorrosion points of ndfeb magnet

by:Newland     2020-05-05
In many products, anti-corrosion is always a problem to be reckoned with, as many magnet ndfeb magnet manufacturers more common type of magnet, ndfeb is very easy to corrode, also because of this, the anti-corrosion measures are necessary, most of finished product to the plating or coating. Regular use of surface treatment include: nickel plating ( Nickel and copper nickel) , galvanized, aluminum plating, electrophoresis, etc. If the work in a closed environment, also can adopt the way of phosphating. Let's together to get to know the summary of anticorrosive points: ndfeb is powder metallurgy products, processing methods and samarium cobalt is similar. At present, the summary of the highest working temperature at 180 degrees Celsius. If it is a bad environment application, generally recommend no more than 140 degrees Celsius. Features: with usually compared with ferrite magnetic materials such as ndfeb magnets have 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 has a very high saturation magnetization Bs ( b = 16公斤) HA and magnetocrystalline anisotropy field ( 哈= 73 koe) , magnetic products are widely used in packaging, toys, gifts crafts, fitness magnetron cars, motors, micro-motor, camera, computer, clocks and watches, audio, instruments, meters, motorcycles, home appliances, office automation, magnets and various fields of daily life. Ndfeb magnet is widely used at present, fast-growing magnet products. From invention to now widely used, but also more than 20 years of time. Because of its high magnetic and workability, the price is not high, so the application area to expand rapidly.
