China Neodymium And Ferrite Magnets Manufacturer & Supplier 
It's happy Friday again, and today we are introducing you to what elements are rare earth magnets usually made of? What is the percentage of each rare earth element?
Rare earth magnets, that is, permanent magnets that contain rare earth components, they are usually more expensive, common rare earth magnets are neodymium magnets and samarium cobalt magnets, the rare earth components in them are different.
Let's start with rare earth neodymium magnet, its rare earth element is neodymium, which is used to provide high magnetic properties. There are also other elements such as iron and boron, which provide magnetic permeability and lattice stability.
In neodymium magnets, the element neodymium accounts for about 29-32.5%.

Rare earth samarium cobalt magnets, what are its rare earth elements?
In samarium cobalt magnets, the rare earth element is samarium, which accounts for about 23-28% and is mainly used in high temperature environments.
Rare earth elements provide excellent magnetic properties for magnets, while transition metal elements and other elements contribute to the formation of a suitable crystal structure and magnetic moment orientation, thus giving the material excellent permanent magnetic properties.
As a permanent magnet manufacturer, we can process all kinds of high-precision, mini, ultra-thin rare earth permanent magnets for you, welcome to provide drawings or size information for inquiry.
