Ferrite Magnets

Ferrite Magnets

Information

Ferrite is the most widely used permanent magnet material. It is manufactured by powder metallurgy. It is mainly divided into barium material (Ba) and strontium material (Sr), and is divided into two types: anisotropic and isotropic. , Is a permanent magnet material that is not easy to demagnetize and not easy to corrode. The maximum working temperature can reach 250 degrees Celsius. It is hard and brittle. It can be cut and processed by tools such as diamond sand, and it can be formed at one time with a mold that is just processed by alloy. Such products are widely used in permanent magnet motors (Motor) and speakers (Speaker) and other fields.
