What's ferrite magnets?

Ferrite magnets are made of the cheapest and most popular of magnetic materials worldwide. The raw materials are iron oxide and strontium carbonate. Hard ferrite magnets can be isotropic and anisotropic. Anisotropic ferrite magnets have an energy density that is more than 300% higher than the isotropic magnets. We make ferrite magnets in block, ring and disc and other shapes.
