Description

Neodymium Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). The NdFeB magnets are the strongest type of magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.

The NdFeB magnets are anisotropic sintered magnets – the alloy is jet milled to a fine powder and is then compacted in the presence of a magnetic field to give it a preferred direction of magnetisation (making it anisotropic in performance). The NdFeB magnets are then sintered to fuse the powder together before final machining and magnetising produces the completed super strength Neodymium magnet.

The Neodymium magnets are also known as Neo magnets, Neodymium Iron Boron magnets, Neodymium-Iron-Boron magnets, NdBFe magnets, NdFeB magnets, NIB magnets, Super Strength magnets and Rare Earth magnets (please note that SmCo is also called a Rare Earth magnet). NdFeB is called a Rare Earth magnet because the Neodymium is a Rare Earth element, having a value of *0 on the Periodic Table. For note, there is nothing rare about Rare Earth magnets – the required elements are readily available and the NdFeB magnets are produced in several hundreds of tonnes each year.
