Ferrite Magnets

Ferrite magnet is a sintered permanent magnet material, which is composed of barium and strontium iron. In addition to strong demagnetization resistance, this kind of magnet has the advantage of low cost. Due to low cost, ferrite magnet has a wide range of applications, from motors, speakers to toys, crafts, so it is the most widely used permanent magnet material.

Description	Ferrite magnet or ceramic magnet is the cheapest magnetic material available with the lowest cost/energy ratio, also known as Ceramic Magnets, they are mainly Strontium based (SrFe2O3), manufactured with Strontium Carbonate additive to increase performances from the obsolete Barium based (BaFe2O3). Their good coercive force results from high crystal anisotropy of Strontium iron oxide. However, isotropic parts can also be produced where a simple and easy multi-pole magnetization is required. The most common shapes are simple, such as blocks,cylinders, rings and arcs. Ferrite is not conductive and has high resistance against corrosion, acids, salts, lubricants.
