What are rare earth magnets? And what are non-rare earth magnets? Are you still confused, today this article takes you through the process, including their differences.
What is the meaning of rare earth magnets?
Rare earth magnets are strong magnetic materials made from rare earth elements, where the rare earth elements are the lanthanides and actinides in the periodic table, which have a special electronic structure that makes them excel in magnetism. Major rare earth magnets include alloys such as neodymium-iron-boron (NdFeB) or samarium-cobalt (SmCo), which have extremely high magnetic properties and are used in a wide variety of applications, including electronic devices, disk drives, electric vehicle drive systems, medical equipment, acoustic equipment, and more.
It is important to note that the rare earth elements in rare earth magnets are not always rare, but rather because of their relatively small distribution in the earth's crust. However, the process of producing and extracting these magnets can have environmental and resource implications.

What is non-rare earth magnet?
Non-rare earth magnets usually refers to the magnet materials that do not contain rare earth elements, has a long history, compared with rare earth magnets, their magnetic properties are relatively weak, but have a certain stability and corrosion resistance, usually used for the magnetic requirements are not high or special environmental applications, typical non-rare earth magnets are ceramic ferrite magnets, alnico magnets, ferrochrome cobalt magnets, rubber magnets and so on.
The above is a little introduction about rare earth magnets and non-rare earth magnets, our long-term supply of a variety of permanent magnets, customers who need samples, quotations are welcome to consult the Courage magnet manufacturers.
