NdFeB magnets are very easy to be corroded. Therefore, most of the finished product should be electroplating or painting. Strong magnet manufacturers said the conventional surface treatment include: nickel, zinc, aluminum, electrophoresis and so on. If you work in a closed environment, you can also use the way of phosphating.
NdFeB magnet is currently widely used, the rapid development of magnet products. NdFeB from invention to now a wide range of applications, but also more than 20 years time. Because of its high magnetic properties and ease of processing, the price is not high, so the application of rapid expansion. At present, the commercial neodymium iron boron, magnetic energy product can reach 50MGOe, is 10 times of ferrite.
NdFeB is also a powder metallurgy products, processing and samarium cobalt similar. At present, the maximum working temperature of NdFeB is about 180 ℃. If it is harsh environment, it is generally recommended not to exceed 140 ℃.
NdFeB magnet Features: Compared with the permanent magnet materials such as ferrite, the NdFeB magnet has very excellent magnetic properties. Its magnetic energy product is much higher than other types of magnets, which can be called "generation of magnetic king". NdFeB magnets with high saturation magnetization and magnetocrystalline anisotropy field, NdFeB magnet products are widely used in packaging, toys, gifts crafts, fitness magneto, motors, micro-motors, computers, instruments, meters, Motorcycles, cameras, clocks and watches, audio, home appliances, office automation, magnetic therapy and everyday life.
As NdFeB high magnetic properties, in many occasions, is used to replace other magnetic materials, to reduce the product size.
