All About Neodymium Magnets

Neodymium magnets are rare types of magnets found on earth. They are considered permanent and are made out of a combination of alloys of iron, boron, and neodymium.

The mixture of these three alloys provides two more names for which the magnets are called – the NIB magnet or the NdFeB magnet. Nd is the chemical symbol for neodymium; Fe is for Iron while B is for boron. Now, these magnets are also considered the strongest of all permanent magnets.

In order to appreciate more about this industrial product, it pays to take a look at the manufacturing techniques and how it is produced. Furthermore, learning about its applications is also an essential part of knowing more about the neodymium magnet. These facts are presented as follows.

Manufacturing techniques for neodymium magnets

It was General Motors Corporation together with the efforts of the Academy of Science and Sumitomo Special Metals that discovered the combination of neodymium, iron and boron compounds to form a permanent magnet. This event in history took place in 1982. The discovery was brought about by the increasing cost of permanent magnets used by SmCo.

General Motors adopted a manufacturing technique known as the melt-spun nanocrystalline. Sumitomo Special Metals, on the other hand, made use of the so-called full-density sintered technique.

These two companies progressed with the use of their different manufacturing techniques for the permanent magnet. Now, General Motors have its own way of commercializing this product by distributing the permanent magnets to manufacturers of bonded magnets while Sumitomo's production is being used in Hitachi Corporation.
