Neodymium NdFeB rare earth magnets are sintered by powder metallurgy with chemical composition of Nd, Fe, B and other minor elements.
Neodymium Iron Boron (NdFeB) magnets are composed of Nd, Fe, B, Dy, Co and other minor elements. NdFeB neodymium magnets are the rare earth magnets with the highest magnetic performance and coercive force in the world.

Neodymium NdFeB magnet have excellent magnetic properties and are extremely strong for their small size. NdFeB magnets are more sensitive to temperature changes, ranging from 0.10%/°C – 0.13%/°C. NdFeB magnets are permanent magnets with the highest maximum energy product. Over the last 10 years, due to the high ratio of performance over price of the NdFeB magnets, NdFeB magnets have become extremely popular in almost all high technology applications that require high performance magnets, motors, sensors, computers, communications, medical equipment, meters, home appliances and so on.

Arc Countersunk Hole Neodymium Magnet NdFeB magnets are mechanically stronger than Sm-Co magnets and less brittle than ceramic & AlNiCo magnets. However, sintered NdFeB magnets are very easy to be corroged. Therefore, Neodymium NdFeB magnets have to be protected with a special coating, such as Zn, Ni, Ni-Cu-Ni, or epoxy. In general, sintered NdFeB magnets need some finish machining to meet the final tolerance.
