Ferrite magnet

Ferrite magnets are mainly made of SrO or BaO and Fe2O3 as raw materials. Ferrite magnets are hard and brittle and have low magnetic energy. However, it is not easy to demagnetize and corrosion, the production process is simple and the price is low, so the ferrite magnet in the whole magnet industry has a high output and is widely used in industrial production.

Ferrite magnet is a metal oxide with ferromagnetism. Generally speaking, the resistivity of ferrite is much larger than that of metal, alloy magnetic materials, but also has higher dielectric properties.

At high frequency, it has high permeability, so it has become a widely used non-metallic magnetic material in the field of high frequency weak current.
