Composite hard magnet NdFeB materials were made using powdered rapidly quenched Nd-Fe-B (MQP-B) and polymers (bakelite). The proportion of the polymer matrix was varied (2.0, 5.0, 7.0, and 10 wt.%). The composite hard magnet NdFeB materials were compacted using one-sided uniaxial hot pressing at 160 ℃ for 20 min. The bulk density of the composite hard magnet NdFeB was measured using the Archimedes method. Compression tests were carried out using the Universal Testing Machine. The results show that a permanent magnet composite with a 2 wt.% bakelite binder composition exhibits higher bulk density and superior magnetic parameters (i.e., remanence, coercivity, and energy product), but slightly lower compressive strength of approximately 845 ㎏f/㎠.
