Sintered Ferrite magnet, Hard ferrite magnet, ferrite permanent magnet

Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative
to metallic magnets. Even though they exhibit low energy (compared with other
permanent magnet materials) and are relatively brittle and hard, ferrite magnets
have won wide acceptance due to their good resistance to demagnetization, excellent
corrosion resistance and low price per pound. In fact, measured by weight,
ferrite represents more than 75 percent of the world magnet consumption. It is
the first choice for most types of DC motors, magnetic separators, magnetic resonance
imaging and automotive sensors.

Besides industrial application, hard ferrite magnets are widely use in educational
areas. We supply industrial use hard ferrite magnets and educational hard ferrite
magnets according to customers' requirements.
