Y30BH Arc Ceramic Magnet

Ferrite Arc Magnet

Ferrite Arc magnets, also known as ceramic magnets, were developed in the 1960’s as a low cost

alternative to metallic magnets.Ferrite magnets have won wide acceptance due to their excellent

corrosion resistant and good resistance to demagnetization. Despite their relatively low energy output,

ferrite magnets’ popularity is largely from its low price. It is the first choice for most automotive sensors,

MRI machines, DC motors, and magnetic separators. In fact, based on weight,it is the most widely

used permanent magnet available today.

Charcteristics
Ferrite magnets are very hard and brittle. Like all magnetic materials, ferrite magnets should not be

used as a structural element in your design. Ferrite magnets are prone to cracking if your application

requires regular impact or flexing. Because ferrite magnets offer good corrosion resistance,

they do not require an outer coating. In rare instances a thin outer coating

is applied simply to protect the material.

Fairly strong magnetic power (Power-Index(1) = 4~5)
Most common used magnet with low cost (Cost-Index(2) = 1~3)
Isotropic & Anisotropic available
Produced by powder metallurgical engineering with chemical composition of Ba/Sr O.6 Fe2O3
Very brittle & relatively hard
Good resistance to demagnetization
Good temperature stability
Oxided to saturation with excellent corrosion resistance

Service temperature greater than rare earth and lower than alnico

Finishing requires diamond cutting or grinding wheel
Energy product lower than alnico and rare earth magnets

Applications of Ceramic Magnets
• Speaker magnets
• DC brushless motors
• Magnetic Resonance Imaging (MRI)
• Magnetos used on lawn mowers, outboard motors
• DC permanent magnet motors (used in cars)
• Separators (ferrous material from non-ferrous)
• Used in magnetic assemblies designed for
lifting, holding, retrieving and separating
