Neodymium magnets, also known as NdFeB magnets, are tetragonal crystals formed by neodymium, iron, and boron (Nd2Fe14B). This type of magnet is the second most magnetic permanent magnet after absolute zero holmium magnet today, and it is also the most commonly used rare earth magnet.

NdFeB is divided into two types: sintered NdFeB and bonded NdFeB. Bonded NdFeB has magnetism in all directions and is resistant to corrosion;

The sintered NdFeB is easy to corrode, and the surface needs to be plated. Generally, there are galvanized, nickel, environmentally friendly zinc, environmentally friendly nickel, nickel-copper-nickel, and environmentally-friendly nickel-copper-nickel. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, which are determined according to the required working surface.

For cutting large NdFeB magnet, many manufacturers use reciprocating long-wire cutting, while small NdFeB magnet is cut with an Inner diameter cutting machine. The cutting efficiency of the Inner diameter cutting machine is low, but sometimes cutting a small amount of NdFeB magnet does not require turning on a large machine. With the rise of diamond wire loop saw, some manufacturers began to use diamond wire loop saw to cut NdFeB, the cutting efficiency is 3 times that of the Inner diameter cutting machine, which has been welcomed by many manufacturers in China.

Sintered NdFeB permanent magnet materials have excellent magnetic properties and are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields.

The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and meters.
