Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets

Grain Boundary Diffusion is an important new advance in Neodymium magnet production technology.    Heavy Rare Earth Elements (HREE) are delivered directly to critical areas of the magnet’s microstructure. These areas are where HREE are the most effective at increasing the properties of the magnet to withstand high opposing magnetic fields at high temperatures. HREE […]

Neodymium vs Ferrite Magnets

A central question that comes up in a magnet trade study is how to decide whether to use a Neodymium magnet or a ferrite magnet for a particular application. A trade study that seems very simple at first glance can quickly become more complex once all the factors are considered. Neodymium vs ferrite magnets? Designers who […]

How Are Neodymium Magnets Made?

Neodymium magnets are made by a sophisticated process that includes some very high-tech metallurgical methods comprising powder metallurgy and advanced process metallurgy.

Dozens of process steps must be followed very precisely to make Neodymium magnets –also known as NdFeB -for the chemical symbols of Neodymium, Iron and Boron.
