MAGNET 25X10X6 BLACK

Ferrite Magnets are also known as Ceramic Magnets, Ceramic Ferrite Magnets, Feroba Magnets and Hard Ferrite Magnets. Ceramic Ferrite magnets are one of the most widely used permanent magnet materials in the world. Ferrite magnets are a low cost magnet material perfectly suited for higher volume production runs . They are termed ceramic due to their excellent electrical insulation ability. Ferrite magnets are superb in damp, wet or marine environments – Ferrite magnets are corrosion free. Because the iron is already in a stable oxidized form in its structure, the iron cannot oxidize (“rust”) any further when in water.

Ferrite magnets can be used at temperatures up to a maximum of +250 degrees C (in a few situations perhaps up to +300 degrees C). There are presently 27 grades of Ferrite Magnet available. The two main grades used today are C5 (also known as Feroba2, Fer2, Y30 and HF26/18) and C8 (also known as Feroba3, Fer3 and Y30H-1). C 5 / Y30 is a general choice of Ferrite Magnet for applications such as over band magnets. C8 / Y30H-1 is a better choice for applications such as loudspeakers and sometimes also motors (C8 has a similar Br to C5 but has a higher Hc and Hci).
