Description

Technical Field

[0002] Neodymium iron boron (NdFeB) magnets, also known as neodymium magnets, with the chemical formula Nd2Fe14B, are man-made permanent magnets. They are tetragonal crystals formed from neodymium, iron, and boron, possessing extremely high magnetic field strength and magnetic energy product. They are among the strongest permanent magnets currently available. Their high coercivity determines their wide range of applications. They are also heat-resistant, with some types of NdFeB magnets capable of operating at temperatures above 500°C. Among rare-earth permanent magnets, NdFeB exhibits high corrosion resistance (except for oxidizing acids). They are small in size, lightweight, easy to machine and transport, and highly customizable, allowing for customization to suit different applications.
