4 Major Causes of NdFeB Magnets Rusting

After buying a strong magnet of NdFeB, many customers found that there was no rust on the magnet for a long time. So what caused the magnet to appear rust? The following is a small series of manufacturers of MPCO magnets to answer your questions!

NdFeB Magnets Rusting

After a period of time, the neodymium iron boron strong magnet will appear white or other color spots on the surface, and will gradually develop into rust spots. Under normal circumstances, it is not easy to appear rust spots when plating magnets are plated, and rust spots appear. The reasons for this are generally the following:

1. The magnet is stored in a place with humidity, poor air circulation and temperature difference;
2. The dirt on the surface of the magnet before plating is not well cleaned;
3. Insufficient plating time or process flow issues;
4. Magnet oxidation caused by damage to the package seal of the magnet;

Generally, the qualified electroplating products produced by NdFeB magnets are not rust-proof under normal conditions, so the most important issue is the way of storage. In places where the humidity is too humid and the air flow is not good, or when the temperature difference changes greatly, even a strong neodymium iron boron magnet that has passed the salt spray test may cause rust spots when stored in a harsh environment for a long time. Therefore, electroplated products should not be placed in high humidity for a long time and should be placed in a cool, dry place.

MPCO NdFeB strong magnet manufacturer has been focusing on producing all kinds of high-difficult, high-precision NdFeB magnets for ten years. It can be customized according to industry requirements, any size, size and performance. If you still want to know more about magnets, please EMAIL US: sales@mpcomagnetics.com
