Neodymium Iron Boron Cube is an alloy made mainly from a combination of Neodymium, Iron, Boron, Cobalt and varying levels of Dysprosium and Praseodymium.
The exact chemical composition within NdFeB depends on the grade of NdFeB. Dysprosium and Praseodymium are added as a replacement for some of the Neodymium to improve the corrosion resistance and to improve the Hci (Intrinsic coercivity) of the “Neo”. An example of the composition is given below.
Typical composition of NdFeB alloy
Main Elements within NdFeB
Percentage by weight
Neodymium (Nd)
29% – 32%
Iron (Fe)
64.2% – 68.5%
Boron (B)
1.0% – 1.2%
Aluminium (Al)
0.2% – 0.4%
Niobium (Nb)
0.5% -1%
Dysprosium (Dy)
0.8% -1.2%

The method of manufacture of Neodymium Iron Boron magnets is as follows:-
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.
