Ceramic (Ferrite) Magnets

Highly Effective, and Cost-Efficient!

Ceramic (also known as "Ferrite") magnets are the lowest cost, hard magnets available today. They exhibit good resistance to demagnetization and to corrosion. Ceramic magnets are hard and brittle and often used in many consumer products such as the back of refrigerator magnets, in tools, motors toys, etc. See below for more detailed information about this material-


Ceramic Magnet Quick Tips

  • Characteristics: Ceramic magnets are medium in magnetic strength, can be used at fairly high temperatures, and low cost making them ideal for applications such as automotive sensors, magnetic separators, craft projects, badge holders, latches, display boards, science projects, toys, games & more..

  • Grades: Grades 5 (most commonly used) through 8 are available in disc, rectangle (block) & ring shapes, and can be custom manufactured to meet your specialty requirements
  • Temperature: Ceramic magnets can be used at fairly high temperatures, although their magnetic properties drop with temperature. At 175° C (350° F), approximately 75% of their room temperature magnetic properties are retained.

  • Machining: Ceramic Magnets are hard & brittle, and can chip or break if dropped or snapped so please take special care when handling these magnets! They require special machining techniques, and should be machined in an “un-magnetized” state. We are fully equipped to machine these materials to your specifications. Just let us know what you are looking for by clicking on the “Special Request” button at the top of the site.

  • Coating: Ceramic magnets do not need to be protected for surface rust. A thin film of magnet powder on the surface is common.
  • Bonding: Ceramic magnets are often assembled into products using "superglues" such as Loctite 325 or other epoxies. Always ensure that bonding surfaces are clean and dry prior to bonding.

  • Safety Precautions: Ceramic Magnets are hard & brittle, and can chip or break if dropped or snapped so please take special care when handling these magnets! They
