These tiny circular D2 x 0.8 ferrite round magnets are sintered permanent magnet materials, consisting of barium and strontium ferrite, which have the characteries of stable strong magnetic, electrical conductivity, thermal stability. Ferrite magnets are stiff and brittle and require special machining processes. The magnetic energy product ranges from 1.1 MGOe to 4.0 MGOe.
This circular ultra-small ferrite round is only 2 mm in diameter and 0.8 mm in thickness, it has the characteristics of small size and high performance. Due to it low cost, ferrite magnets have a wide range of applications. It often used in applications likes crafts, souvenirs, toys and refrigerators. And they are also used in motors, sensors, speakers, meters, instruments, and medical devices, so they are the most widely used permanent magnet material today.
What are the types of ferrite? Can they be divided into isotropy and anisoytopy?
Ferrite can be by divided into two types: isotropy and anisotropic. Isotropy ferrite magnets can be magnetized along any direction because they are not oriented, while anisotropic magnets need to be magnetized along the direction they are taken because they are oriented along the manufacturing direction. The anisotropic magnetism is stronger than the isotropy one.
Ferrite magnets by production process can be also divided into sintered ferrite magnets and bonded ferrite magnets according to the manufacturing process. Bonded ferrites also contain two main categories of injection molded ferrite magnets and rubber magnets.
In addition, Ferrite magnets by shape can be also divided into ferrite round magnet, ferrite block magnets, ferrite arc segment magnets, ferrite ring magnets and other irregular shape magnet.
