What are permanent magnets made of?
Modern permanent magnets are made of special alloys that have been found through research to create increasingly better magnets. The most common families of magnet materials today are ones made out of Aluminum-Nickel-Cobalt (Alnicos),Strontium-Iron (Ferrites, also known as Ceramics), Neodymium-Iron-Boron (Neo magnets, sometimes referred to as “super magnets”), and Samarium-Cobalt. (The Samarium-Cobalt and Neodymium-Iron-Boron families are collectively known as the Rare Earths.)

Neodymium magnet grades
Neodymium Magnet (NdFeB magnet), referred to as the “King of Magnets”, has so far the highest commercialized performance. It has quite high magnetic properties, whose BHmax is 10 times higher than Ferrite. It is excellent in mechanical performance, and its operating temperature can reach up to 200 degrees Celsius. With its hard texture, stable performance and superior cost-effectiveness, it is widely used. But due to its strong chemical activity, its surface coating must be disposed. Nowadays, neodymium magnets has got rapid development and wide application. In many fields, it may replace the traditional iron magnet, Al nickel and cobalt alloys and samarium cobalt magnets, such as electric motors, apparatus and instruments, automobile industry, petrochemical industry and magnetic health care products. Various shapes can be produced, such as disc magnet, ring magnet, rectangular magnet, arc magnet, and other forms of magnet.Neodymium magnets exists in some everyday electronic products like hard disc, cellphones, and earphones, etc.
Neodymium magnets are most powerful of any kind of magnetic materials Br of Neodymium magnets are much more than 11,000 Gauss. Therefore, Neodymium magnets have strong holding strength on metal surface and could be used as component for holding, separating, etc.
Neodymium magnets must be carefully handled to avoid personal injury and material damage due to its extremely magnetic strength and brittle property.
