The third generation of rare earth permanent magnet NdFeB is the most powerful permanent magnet in modern magnets. It not only has the characteristics of high remanence, high coercivity, high magnetic energy product, high performance-to-price ratio, but also is easy to be processed into various sizes. Now it has been widely applied in various fields.
Strong ring neodymium magnets are used to hang and fix various metal tools, organize various metal objects, and save more living space. Neodymium disc magnets are great for workshop woodworking, garages, tool rooms, cruise ships, garages, kitchens, DIY, and more.
