In order to avoid corrosion, they need to be protected on the surface. Neodymium magnets can resist demagnetization up to a certain temperature (80☌), after which it start losing its magnetization and completely lose it at 310☌. Although neodymium iron boron magnets have the strongest magnetic force in the world and have the largest energy product, exceeding the most powerful samarium cobalt magnets before, they are the only rare earth magnets that require surface coating. Neodymium magnets are also covered with nickel coatings to prevent corrosion of the brittle magnet. It is also followed by letters (M, H, SH, UH, EH), which stated the respective grade's temperature ratings. A number usually indicates a grade after 'N,' such as N38 or N52. The grade of a magnet is allotted respective to its composition, i.e., the high-grade magnet has a composition that enhances its magnetic strength compared to the lower grade magnets. Neodymium magnets are permanent rare-earth magnets which has the highest strength of all the available permanent magnets. Besides the mentioned ones, we can provide our facilities to manufacture any shape on customer's orders. We can customize their sizes according to the specific requirements of the customers. We provide our customers with high-quality and licensed interests in various required forms, i.e., disc, square, rectangular, beads, cylinder, trapezoid, and ring-shaped magnets. Neodymium (NdFeB) magnets of various grades and shapes are available for our customers. Our NdFeB magnets are very reliable, user-friendly, and cost-effective. We manufacture a range of different grading neodymium magnets in various shapes. Neodymium magnets are preferred over other types of magnets because of their low cost and efficient magnetic ability. NdFeB magnets are of great importance as they are used in modern technology, i.e., in hard disk, magnetic fasteners, automatic locks, cordless tools, medical diagnosis-based machines. These magnets are available in diverse forms, i.e., circles, rings, cylinders, beads, blocks, slits, etc. In 1984, general Motors and Sumitomo special metals manufactured neodymium (NdFeB) magnets for the first time. These are the strongest permanent rare-earth magnets and are used widely. Neodymium magnets are also named NdFeB magnets because of their composition, i.e., neodymium (Nd) alloy, Iron (Fe), and Boron (B). Dailymag is professional Rare Earth NdFeB Magnet manufacturer and exporter in China.
