Neodymium Magnets (rare earth)
Neodymium iron boron (rare earth) is the highest strength magnet material available.
Use where space is it a premium or a very high level of magnetism is required.
The material itself is brittle and has poor corrosion resistance. To counter this it is usually coated or supplied as a magnetic assembly (the magnet material is contained in a metal ‘pot’ – see our Neodymium magnet assemblies.
Neodymium magnet features
High power
Low maximum operating temperature – 100 degrees
Neodymium magnets are very brittle and must be handled with care. All are anisotropic (the magnet strength is strongest in one direction).
Alloys are available which increase maximum operating temperatures but at the expense of magnet strength. Please contact us for more information about this and custom sizes.

What is the history of neodymium?
Neodymium was discovered by Baron Carl Auer von Welsbach, an Austrian chemist, in Vienna in 1885. He separated neodymium, as well as the element praseodymium, from a material known as didymium. Neodymium was not isolated in a relatively pure form until 1925. The name neodymium comes from the Greek words neos, new, and didymos, twin.
Neodymium is primarily obtained through an ion exchange process of monazite sand ((Ce,La,Th,Nd,Y)PO4), a material rich in rare earth elements, as well as through electrolysis of its halide salts.

What else is Neodymium used for?
Neodymium is a component of didymium used for coloring glass to make welder’s goggles.
Neodymium colors glass in delicate shades ranging from pure violet through wine-red and warm gray. Light transmitted through such glass shows unusually sharp absorption bands; the glass is used in astronomical work to produce sharp bands by which spectral lines may be calibrated. Neodymium is also used to remove the green color caused by iron contaminants from glass.
