Ferrite magnets have a natural grey ceramic finish. Ferrite magnets are stronger than Alnico and have much better corrosion resistance than Rare Earth. Ferrite magnets were developed as a low cost alternative to metallic magnets and have been manufactured since 1954. Although they provide less energy than other magnets available today (see our Rare Earth magnets for higher strength), Ferrite magnets are frequently selected for their stability, tolerance against demagnetisation, outstanding corrosion resistance and their low price per magnetic output
