NdfeB magnets (neodymium iron boron magnets) made from an alloy of neodymium, iron and boron, are considered to be the strongest rare earth permanent magnets worldwide. The strong attraction of neodymium magnets are out of proportion to its small size and the magnets can be easily processed into various shapes. Such as rings, blocks, discs and robs. In addition, their lightweight, strength, consistency of the magnetization and high resistance to demagnetization has made neodymium magnets the most popular choice for a wide application.
Neodymium (also known as "NdFeb", "NIB" or "Neo") disc magnets are the most powerful rare-earth magnets available today. Available in disc and cylinder shapes, Neodymium magnets have magnetic properties that far exceed all other permanent magnet materials . They are high in magnetic strength, moderately priced and able to perform well in ambient temperatures. As a result, they are the most widely-used Rare-Earth magnets for industrial, technical, commercial and consumer applications.
