Anti-corrosion points of NdFeB strong magnets

In many products, anti-corrosion has always been a problem that cannot be ignored. As a common type of magnet for high-strength magnet manufacturers, NdFeB strong magnets are also indispensable. Therefore, NdFeB magnets are very easy to be corroded, and because of this, most of the finished products need to be electroplated or painted. Commonly used surface treatments include: nickel plating (nickel copper nickel), zinc plating, aluminum plating, electrophoresis, etc. If working in a closed environment, phosphating can also be used. Let's take a look at the main points of anti-corrosion of NdFeB strong magnets:

Anti-corrosion points of NdFeB magnets

NdFeB is also a powder metallurgy product, and the processing method is similar to that of samarium cobalt. At present, the working temperature of NdFeB is around 180 degrees Celsius. If it is a harsh environment application, it is generally recommended not to exceed 140 degrees Celsius.

Features of NdFeB magnets: Compared with Permanent Magnet materials such as ferrite, NdFeB strong magnets have excellent magnetic properties. Its magnetic energy product is much higher than other types of magnets, so it can be called "a generation of magnet king". NdFeB strong magnets have very high saturation magnetization Bs (Bs=16KGs) and magnetocrystalline anisotropy field HA (HA=73KOe), NdFeB Strong Magnet products are widely used in packaging, toys, gift crafts, fitness magnets Control cars, motors, micro motors, cameras, computers, clocks, audio, instruments, meters, motorcycles, home appliances, office automation, magnetic therapy and various fields of daily life.

The above are the anti-corrosion points of NdFeB strong magnets that we have introduced in detail for you. NdFeB strong magnets are currently widely used and rapidly developing magnet products. It has only been more than 20 years since NdFeB has been widely used since its invention. Due to its high magnetic properties and ease of processing, the price is not very high, so the application field is expanding rapidly.
