Ceramic Ring Magnets

Ceramic (hard ferrite) ring magnets are among the most economical magnets available, and are commonly used in manufacturing, craft and hobby applications.


  • Ceramic rings 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 gray 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 5, magnetized through the thickness. Grade 8 is also available by request; that is generally used in more demanding technical applications.
  • For a comparison of Ceramic Grades 5 & 8, please see our Chart of Properties.
