Rare Earth Disc Permanent Ndfeb Magnet
Since neodymium magnet material is prone to chipping and cracking, it does not lend itself to conventional machining methods. However, neodymium can be abrasively ground, but only with the use of liberal amounts of coolant. The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust.
A powder metallurgy process is used in producing sintered Neodymium magnets. Although sintered Neodymium is mechanically stronger than Samarium Cobalt magnets and less brittle than other magnets, it should not be used as a structural component. Selection of Nd-Fe-B is limited by temperature due to its irreversible loss and moderately high reversible temperature coefficient of Br and Hci.
