If the strong neodymium iron boron magnet is not stored properly, white or other colored spots will appear for a long time, and rust spots will develop over time. Under normal circumstances, the coating of Aoisawa strong neodymium iron boron magnets is not prone to rust spots. The usual reasons for rust spots are as follows:

1. The magnet is stored in a place with humidity, poor air circulation, and temperature differences;

2. The dirt on the surface of the magnet before electroplating is not well cleaned;

3. Insufficient electroplating time or process flow problems;

4. Magnet oxidation caused by broken magnet packaging seal;

Xiamen everbeen magnet manufacturers

For the qualified electroplating products of Xiamen everbeen neodymium iron boron strong magnet, under normal circumstances, there should be no rust spots on the surface of the electroplating coating of the magnet. The following storage methods should be avoided for NdFeB strong magnets:

In places that are too humid and air circulation is not good; when the temperature difference changes greatly, even if the salt spray test qualified product is stored in a harsh environment for a long time, rust spots may occur. When the electroplating product is stored in a harsh environment, the base layer will further react with the condensed water, which will cause the bonding force of the base layer and the plating layer to decrease. In severe cases, it will cause the base to partially powder and then naturally peel. Electroplating products should not be placed in a place with high humidity for a long time, but should be placed in a cool, dry place.
