Even though they are called “rare earth” or “neodymium” magnets, they contain a lot iron and other metals. All of the neodymium, iron, samarium, cobalt, nickel, etc comes from the ground.
Grinding and Mixing the Alloy
Once the raw material is available, it must be ground to a powder and mixed to create the various grades of materials. Different mixtures will create materials with various magnetic properties. Some are stronger, others more durable, and others can last longer in high temperatures.
High Energy No Coating Block Magnets N33AH Pressing
The next step is to press the mixture together into a form.
We use a large electromagnet to optimize the pressed mixture for magnetization.
Once the particles are aligned, we can sinter the material to firmly lock everything in place.
Neodymium Iron Boron magnets were commercially introduced in the early 1980s. They are widely used today in many different applications. The cost of this magnet material (on a dollars per energy product basis) is comparable to that of Ferrite magnets. On a dollars per pound basis, the cost of Neo magnets is about 10 to 20 times that of Ferrite magnets.
Note that NdFeB magnets are covered by various patents (held by Neomax) and only licensed materials are allowed into the USA. There are a number of sources that do sell unlicensed products to those willing to purchase them. HSMAG does not sell unlicensed materials.
Very high strength
Relatively low cost (by weight about 20 times Ferrite magnets, by “Dollars per BHmax” about 1.5 times Ferrite magnets).
Relatively easy to machine, compared to Alnico and SmCo magnets.
