Prepare by pulverizing an ingot precursor and liquid phase, sintering the magnetically aligned powder into dense blocks
then heat treat, cut to shape, surface treat and magnetize.
Melt spin a thin ribbon of the Nd-Fe-B alloy.
pulverize ribbon into particles
mixed with polymer
either compression or injection mold into bonded magnets
... i had to buy 100 of them because they are RARE EARTH MAGNETS.
