Measurements

Ceramic magnet material is very hard and brittle. On average the material’s hardness is 7 on the Moh scale and conventional machine tools and cutters are not appropriate. Diamond tooling and some abrasives are the conventional means of fabrication for this magnet alloy. Most magnet materials are machined in the un-magnetized state. Once the fabrication and cleaning operation are complete the magnet is then magnetized to saturation.
Ceramic magnets are fairly easy to magnetize and only require a reasonable magnetizing field. They are usually used in conjunction with a mild steel element such as a motor housing or backing-plate. Normally it is desirable to magnetize the Ceramic magnet installed on/in this element.
Ceramic magnets are inherently brittle. Ceramic magnets are particularly prone to cracking when the application involves impacts or flexing. Like all magnetic materials, ceramic should not be used as a structural element in a design.
