Ferrite Magnet---As important parts of magnetic materials, hard ferrite materials play a heavyrole in electronic industry, electronic information industry, car industry, motorcycle industry etc. meanwhile, they are also widely used in medical treatment, mining and metallurgy, industrial automation, oil energy industry and civil industry. ferrite magnet, Ferrite Magnets, bonded ferrite magnet, barium ferrite magnet, hard ferrite magnet, sintered ferrite magnet, bonded ferrite injection magnet
Ceramic (ferrite) magnets are composed of SrO or BaO and Fe2O3. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs or segments for motors.
Attributes of Ceramic Magnets:
Least expensive material compared to alnico and Rare Earth Magnets
High intrinsic coercive force
Available in simple shapes only due to manufacturing process
Lower service temperature than alnico, greater than rare earth
Lower energy product than alnico and rare earth magnets
For as pressed material, tolerance on the thickness (direction of magnetization) is ± .005inch. Other dimensions are ± 2% or ± .010inch, whichever is greater.
