How are neodymium magnets made?

Our neodymium magnets, also known as NIB or NdFeB magnets, are comprised of a neodymium, iron, and boron compound referred to as Nd2Fe14B.

This compound is a powdered mixture. It is first poured, then pressed (using extreme pressure) into specially-cast molds. The compound is then sintered (heated under a vacuum), cooled, then ground or sliced into the desired shape.

Next, the magnets are dipped in a specified coating material such as zinc, gold, or the triple-layer nickel/copper/nickel alloy plating.

Finally, the magnets are magnetized by exposing them to an extremely strong magnetic field. This final step is what turns neodymium magnets into permanent magnets, enabling them to perpetually produce their powerful magnetic pull or repel power.
