How long can the magnetic properties of NdFeB Magnets last?

The magnetic properties of Neodymium magnet can last from several years to decades, depending on many factors, including the type of magnet, the quality of the manufacturing process and the actual conditions of use. In an ideal use environment, excellent quality Neodymium magnet magnets can maintain their magnetic properties for decades. However, the magnetic properties of Neodymium magnet will also be affected by many factors, including high temperature, impact, chemical corrosion, etc.

Neodymium Magnet

Types of magnets: Neodymium magnets are a common and highly magnetic magnets, but they are easily damaged in high-temperature environments. In contrast, Samarium cobalt magnets have better thermal stability, so they may have a longer lifespan under high temperature conditions.

Manufacturing process quality: The manufacturing process of magnets needs to be precisely controlled to ensure the consistency and integrity of their micro-structure. High-quality magnets should have a uniform magnetic domain to avoid cracks or other physical defects.

Conditions of use: If magnets are used in a humid, acidic or alkaline environment, oxidation or corrosion may occur, resulting in a decrease in their magnetic properties. Therefore, the magnet must be properly preserved and used in a suitable environment.

High-temperature demagnetization: The working temperature range of Neodymium magnet magnets is 60-200 degrees Celsius, and demagnetization will occur beyond this range. The temperature of the Curie is about 320-380 degrees Celsius, and the magnet will completely lose its magnetism above this temperature.

Impact demagnetization: Neodymium magnet magnets will also demagnetization when they are seriously impacted. Even if they are not broken, the magnetic force will be reduced to varying degrees.

Corrode: If the coating on the magnet is damaged and water enters the interior, the magnet will rust, which will cause a decrease in magnetic properties again. Both Samarium cobalt magnets and ferrite magnets are corrosion-resistant,but their strength is not as strong as neodymium magnets.

In order to maximize the life of Neodymium magnet magnets, the appropriate magnet type should be selected according to the specific application scenario, high-quality magnets should be purchased, and the correct operation and maintenance process should be followed during use and preservation.
