Y20 Y22 Y23 Y25 Y26H Sintered Ferrite Ceramic Ring Magnet
Introduction
Hard Ferrite magnets are commonly known as Ceramic magnets due to the process used to produce them. Ferrite magnets are manufactured mainly of strontium or barium ferrites and iron oxide. Hard Ferrite (Ceramic) magnets are produced as Isotropic and Anisotropic types. Isotropic type magnets are produced without orientation and can be magnetized in any direction. On the other hand, Anisotropicmagnets are exposed to an electromagnetic field during their process to achieve higher magnetic energy and properties. This is done by pressing dry powders or slurry into a desired die cavity with or without orientation. After the compaction into the dies the parts are exposed to a high temperature, a process known as sintering.
