Y30 Hard Sintered Disc Ferrite Magnet

Y30 Hard Sintered Disc Ferrite Magnet As important parts ofmagnetic materials, hard ferrite (ceramic) magnets play an important role inelectrical engineering, electronic information, car, motorcycle industries etc.They are also widely used in medical treatment, mining and metallurgy,industrial automation, oil energy and civil industries.  Ceramic magnets are composed of iron oxide, barium and strontium elements. Thisclass of magnets has a higher magnetic flux density, higher coercive force, andhigher resistance to demagnetization and oxidation compared to other non-rareearth permanent magnets. The biggest advantage of such magnets is the low cost,which makes the hard ferrite magnets very popular in many permanent magnetapplications. Due to their ceramic nature, ferrite magnets are very hard andbrittle. Special machining techniques must to be utilized for these magnets.
