Diamond wire loop saw cut NdFeB magnet

Diamond wire loop saw cutting NdFeB magnet 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,...
