Measurements
Ceramic (hard ferrite) Ring magnets are among the most economical magnets available, and are commonly used in separation, holding, sweepers, as well as many other applications.
Ceramic Ring Features
Ceramic Ring magnets offer economical magnet power for price sensitive applications when you need low cost, good holding strength and great value.
Ceramic Ring magnets are a dark charcoal grey in color, and do not appear metallic.
Ceramic magnets are not suited for high temperature applications (over 250° C)
We stock ceramic Ring magnets in Grade 8, magnetized through the thickness.
For a comparison of Ceramic Grades 5 & 8, please see our Chart of Properties.
