Ceramic Magnets (Ferrite)

Highly Effective, and Cost-Efficient!

Ceramic magnets (also known as "Ferrite" magnets) are the lowest cost hard magnets available today- used for many consumer & commercial applications: craft projects, refrigerator magnets, badge holders, latches, display boards,motors, lifting magnets, science projects, toys, games, POP displays, advertising giveaways & much more.

Ceramic Magnet Quick Tips

  • Characteristics of Ceramic Magnets: Ceramic magnets are medium in magnetic strength, can be used at fairly high temperatures, and are 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 of Ceramic Magnets: 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 of Ceramic Magnets: 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.

  • Common Applications: craft projects, refrigerator magnets, badge holders, latches, display boards, loudspeakers, security systems, motors, generators & alternators, lifting magnets, eddy current devices, brakes, clamps, switches & relays, sweeper magnets, science projects, toys, games, motors, magnetic couplings, POP displays, advertising giveaways, promotional items, novelties & more.

  • Machining of Ceramic Magnets: Ceramic Magnets are hard & brittle, and can chip or break if dropped or snapped together 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.

  • Ceramic Magnets Coating: Ceramic magnets do not need to be protected for surface rust. A thin film of magnet powder on the surface is common.
  • Ceramic Magnets 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 together so please take special care when handling these magnets!
