NdFeB magnets:

Neodymium magnets are also named NdFeB magnets because of their composition, i.e., neodymium (Nd) alloy, Iron (Fe), and Boron (B). These are the strongest permanent rare-earth magnets and are used widely. In 1984, general Motors and Sumitomo special metals manufactured neodymium (NdFeB) magnets for the first time. These magnets are available in diverse forms, i.e., circles, rings, cylinders, beads, blocks, slits, etc. 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. Neodymium magnets are preferred over other types of magnets because of their low cost and efficient magnetic ability. We manufacture a range of different grading neodymium magnets in various shapes. Our NdFeB magnets are very reliable, user-friendly, and cost-effective.

Basics of Neodymium magnet:
Neodymium magnets are permanent rare-earth magnets which has the highest strength of all the available permanent magnets. You can get them in a range of grades. 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. A number usually indicates a grade after 'N,' such as N38 or N52. It is also followed by letters (M, H, SH, UH, EH), which stated the respective grade's temperature ratings. Neodymium magnets are also covered with nickel coatings to prevent corrosion of the brittle magnet. Neodymium magnets can resist demagnetization up to a certain temperature (80°C), after which it start losing its magnetization and completely lose it at 310°C. 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. In order to avoid corrosion, they need to be protected on the surface. , Such as electroplating with nickel, zinc, tin, gold and spraying epoxy resin on the surface. (SmCo magnet, AlNiCo magnet, Ferrite magnet and Rubber magnet all the surface doesn't need to be protected, and it can be used directly after production and processing)
