Ferrite Magnets

 

WHAT ARE FERRITE MAGNETS?

Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost.

Ferrite magnets are medium in magnetic strength and can be used at fairly high temperatures.

 

HIGH HEAT AND FERRITE MAGNETS

 

For all Ferrite magnets, the degradation of magnetic properties is essentially linear with temperature. Ferrite magnets can be used at fairly high temperatures, although their magnetic properties drop with temperature. At 175° C, approximately 75% of their room temperature magnetic properties are retained.

 

THINGS TO KNOW WHEN USING FERRITE MAGNETS & IMPORTANT SAFETY CAUTIONS

 

Ferrite magnets are hard & brittle, and they can chip or break if dropped or snapped together, so please take special care when handling these magnets

The corrosion resistance of Ferrite is considered excellent, and no surface treatments are required. However, Ferrite magnets may have a thin film of fine magnet powder on the surface and for clean, non-contaminated applications, some form of a coating may be required.

Ferrite magnets require special machining techniques and should be machined in an “un-magnetised” state. We sadly do not offer “Un-magnetised” Ferrite magnets. Therefore, none of our ferrite magnets can be machined.

Ferrite magnets are often assembled into products using "superglues" or other epoxies. Please always ensure that bonding surfaces are clean and dry prior to bonding.

 

APPLICATIONS OF FERRITE MAGNETS

 

Common applications for ferrite magnets include 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.
