If the orientation and temperature of the magnet are satisfactory, it will not happen. NdFeB magnets are also called "strong magnets" and "permanent magnets". If properly deposited, the surface coating is not damaged, and used at a regular temperature, demagnetization will not occur, and the service life is permanent.
In the past 30 years, permanent magnet data has been widely used, which greatly improves the market value of permanent magnet data. Now, NdFeB magnets are widely used. They are very popular not only in electronic products and their packaging leather goods, especially in the maglev industry, which is a proper taste, so many NdFeB manufacturers are derived. For professionals, it is not a problem to distinguish the quality of NdFeB, but for non professionals, how to choose high-quality NdFeB magnets?
1、 First of all, it depends on whether the original data meet the standards and international standards. In order to make a profit, many manufacturers of NdFeB drill holes in the original data to reduce the cost, which will reduce the performance of NdFeB magnets, resulting in uneven magnetic distribution and unstable performance when they are used.
2、 Looking at the production equipment and process flow of NdFeB manufacturers, the two-part limited formation method is generally adopted in the production of NdFeB in China. Advanced skills can not only increase the output, but also improve the quality. Now, SC, HD and JM are relatively advanced skills.
3、 Looking at the scale of NdFeB magnets, the scale is determined by the strength of the factory and the craftsmanship of the master. Because in the process of producing NdFeB, the process is relatively complex and cannot be formed at one time. Through cutting and reprocessing, the scale and shape of magnets used in each profession are different. If you want to satisfy the scale and quality required by the customers, the skills of the NdFeB manufacturers are different Strength is crucial.
4、 The longevity of NdFeB magnet depends on the coating on its surface. In order to prevent the corrosion of weak acid liquid and high temperature oxidation, the general method is to electroplate on the surface of magnet to extend the service life of magnet. The commonly used coating includes nickel, nickel copper nickel, zinc, color zinc, epoxy resin, etc. we can choose different coating according to the different needs of customers.
AISEN MAGNETS focused on development and manufacturing of Neodymium magnet, has more than 10 years manufacturing experience in producing various sizes, different shape and surface coating. Over 45 different grades of neodymium magnet (strong magnet) widely used in many industry.
