NdFeB

NEODYMIUM MAGNET, also known as NdFeB MAGNET, is a tetragonal crystal formed of ruthenium, iron, and boron (ND2FE48). In 1982, Sagawa, a Sumitomo special metal, discovered a neodymium magnet. The magnetic energy product (BHMAX) of this magnet is larger than that of the boring magnet, which is the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metal successfully developed the POWDER METALLURGY PROCESS, and GM successfully developed MELT-SPINNING PROCESS to prepare NdFeB magnets. This magnet is the most magnetic permanent magnet available today and is also a rare earth magnet commonly used. NdFeB magnets are widely used in electronic products such as hard disks, mobile phones, earphones, and battery-powered tools.
In order to avoid the damage of corrosion, the surface of the permanent magnet material needs to be protected during use, such as plating with gold, nickel, zinc, tin, and surface spraying epoxy resin.
