Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternativeto metallic magnets. Even though they exhibit low energy (compared with otherpermanent magnet materials) and are relatively brittle and hard, ferrite magnetshave won wide acceptance due to their good resistance to demagnetization, excellentcorrosion resistance and low price per pound. In fact, measured by weight,ferrite represents more than 75 percent of the world magnet consumption. It isthe first choice for most types of DC motors, magnetic separators, magnetic resonanceimaging and automotive sensors.Besides industrial application, hard ferrite magnets are widely use in educationalareas. We supply industrial use hard ferrite magnets and educational hard ferritemagnets according to customers' requirements. producing area:China payment:T/T supplying capacity:20,000 cartons/month
