Feature	A low cost alternative to other magnetic materials, offers relatively high operating temperatures and good resistance to corrosion& demagnetization. However, it has lower energy levels (Br) and is brittle in nature.
Size tolerance	±0.05mm for diamater /thickness, ±0.1mm for width/ length,which need to contact our engineer!
Applications	Hard ferrite magnets have a wide variety of applications: Speaker Magnets, DC Motors, Sweepers, Magnetic Separators for ferrous materials, Automotive Sensors, MRI's, Reed Switching, Hall Effect Devices, in Assemblies such as (separating, holding, lifting, retrieving, and latching), Refrigerator Magnets and Arts and Crafts as well as many other novelty applications. Hard ferrite must be magnetized in the direction of orientation, which is the same as the direction of pressing.
Description	Ferrite magnet or ceramic magnet is the cheapest magnetic material available with the lowest cost/energy ratio, also known as Ceramic Magnets, they are mainly Strontium based (SrFe2O3), manufactured with Strontium Carbonate additive to increase performances from the obsolete Barium based (BaFe2O3). Their good coercive force results from high crystal anisotropy of Strontium iron oxide. However, isotropic parts can also be produced where a simple and easy multi-pole magnetization is required.  The most common shapes are simple, such as blocks,cylinders, rings and arcs. Ferrite is not conductive and has high resistance against corrosion, acids, salts, lubricants.
