Sintered Hard Ferrite Magnet, HF20/19, Dailymag (CAT#: STEM-GLE-0054-WXH)

Sintered Ferrite magnet (Ceramic Magnets, Hard Ferrite Magnet) 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, Sintered Ferrite magnet (ceramic magnets, Hard ferrite magnet) 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.

Grades: HF20/19
Br(mT): 320-333

The elements of Sintered NdFeB Magnet (Hard Ferrite magnet) are ferric oxide/barium, strontium.
Ferrite has higher coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets.
The biggest advantage of such magnet is their low cost.
