What is the highest magnetic field strength of NdFeB magnets?

Mar 18, 2024 Leave a message

NdFeB magnets are permanent magnets made of neodymium, iron and boron. They belong to the rare earth permanent magnet series and have the highest magnetic properties among all permanent magnets, stronger than ferrite, samarium cobalt and alnico. In addition to high strength magnetic force, it is cost-effective, making it the best choice for consumers, commercial, industrial and technical applications. NdFeB magnets provide maximum performance with minimum magnet size. A coating is applied during processing to prevent the risk of corrosion – NiCuNi, zinc, epoxy and gold are popular finishes.

NdFeB magnets are used in nearly every industry: Mining, Automotive, Aerospace, Wind Power, Military, Appliances, Lighting, Electronics, Separation, Motor and Generator Industries just to name a few examples.

What grades and shapes of neodymium magnets are available?

Neodymium magnets are available in different grades such as N35, N38, N42, N52, N35UH, etc. Each shape of neodymium magnet is graded according to its material. The magnetic force increases with the grade and size of the magnet. The current highest level is N52. The letters after the grade represent the magnet's temperature resistance in high degrees. Magnets without a letter after the grade are the standard temperature of the magnet and are the most widely used on the market.

Therefore, a NdFeB magnet grade without a letter indicates that the maximum operating temperature of the magnet is 80 C. That is to say, its maximum temperature resistance cannot be exceeded during use, otherwise the magnetism will be lost. Our neodymium magnets are REACH and ROHS compliant. They do not contain any SVHC and the neodymium is produced to ISO9001 quality control standards. NdFeB magnets are usually available in block, disc, ring, arc, sphere, triangle, trapezoid, square punch, round punch and many other shapes as stock and custom products.
