Preparation process of sintered NdFeB magnets (3) - orientation forming Magnetic field orientation forming is to use the interaction between magnetic powder and external magnetic field to arrange the easy magnetization direction of powder particles so that it is consistent with the final magnetization direction of the magnet. This is the most commonly used method [...]
Preparation process of sintered NdFeB magnets (4) - Sintering, heat treatment and machining Sintering and heat treatment The blanks pressed by magnetic field orientation are sintered in a high vacuum or pure inert atmosphere to reach a high density close to 95% of the theoretical density. The magnet holes are in a closed structure, which [...]
