n simplified terms, the "Neo" alloy is like a cake mixture with each factory having its own recipe for each grade.

Product Name: NdFeB magnets for motor

The Neodymium metal element is initially separated from refined Rare Earth oxides in an electrolytic furnace. The "Rare Earth" elements are lanthanoids (also called lanthanides) and the term arises from the uncommon oxide minerals used to isolate the elements. Although the term "Rare Earth" is used, it does not mean that the chemical elements are scarce. The Rare Earth elements are abundant e.g. Neodymium element is more common than gold. The Neodymium, Iron and Boron are measured out and put in a vacuum induction furnace to form an alloy. Other elements are also added, as required for specific grades e.g. Cobalt, Copper, Gadolinium and Dysprosium (e.g. to assist with corrosion resistance). The mixture is melted due to the high frequency heating and melting the mixture.

In simplified terms, the "Neo" alloy is like a cake mixture with each factory having its own recipe for each grade. The resultant melted alloy is then cooled to form ingots of alloy. The alloy ingots are then broken down by hydrogen decrepitation (HD) or hydrogenation disproportionation desorption and recombination (HDDR) and jet milled down in a nitrogen and argon atmosphere to a micron sized powder (about 3 microns or less in size). This Neodymium powder is then fed into a hopper to allow the pressing of magnets to occur.
