Is this Neodymium Disc Magnet corrosion-resistant and durable?

The core components of Neodymium Disc Magnets include elements such as neodymium, iron and boron, which can remain relatively stable in dry, non-corrosive environments. However, when they come into contact with water, moisture, certain acids, alkalis or salts, chemical reactions may occur, resulting in surface corrosion or internal performance degradation.
High humidity environments accelerate the oxidation process on the surface of magnets and form an oxide layer, which can slow down further corrosion to a certain extent, but also reduce the magnetic performance of magnets. Extreme temperatures (especially high temperatures) accelerate changes in the internal microstructure of magnets, affect the arrangement of magnetic domains, and thus weaken the magnetic force. At the same time, high temperatures may also promote chemical reactions between magnets and substances in the environment. Corrosive gases (such as chlorine, hydrogen sulfide, etc.) or liquids (such as acid and alkaline solutions) present in certain industrial environments will directly contact the surface of magnets, causing serious corrosion damage.
In order to improve the corrosion resistance of NdFeB magnets, manufacturers usually use a variety of surface treatment technologies, such as electroplating, chemical plating, spraying, etc. These treatments can form one or more layers of protective film on the surface of the magnet, effectively isolating the magnet from contact with corrosive substances in the environment. For example, the electroplated nickel layer is not only beautiful, but also provides excellent corrosion resistance, especially in humid and salt spray environments.
Although NdFeB magnets have extremely high magnetic energy product and coercivity, they are relatively fragile in physical strength. Its crystal structure determines that it has weak resistance to impact and extrusion, and it is easy to break or deform when subjected to external forces. Therefore, it is necessary to avoid direct collision or falling with hard objects during use. In addition to the environmental factors mentioned above, the durability of magnets is also affected by factors such as vibration, impact, and magnetic field interference in its working environment. Long-term exposure to high vibration or strong magnetic field environments may cause disordered arrangement of magnetic domains inside the magnet, thereby reducing magnetic force or failure.
Keep the magnet storage environment dry, ventilated and free of corrosive substances. Avoid exposing magnets to high temperature, high humidity or strong magnetic field environments. When handling and using magnets, they should be handled with care to avoid violent collisions and falls. Regularly check the surface of the magnet for signs of damage or corrosion. If found, timely repair measures or replacement of magnets should be taken. Ensure that the magnets are correctly positioned and firmly fixed during installation to avoid damage caused by looseness or improper position. For special applications or complex environmental conditions, it is recommended to consult professionals or manufacturers for more specific guidance and suggestions.
