Product Description

About ferrite magnets

1.Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets.
2.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.
3.In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption.
