Hard ferrite magnet offer an excellent cost performance ratio and are made mainly from Fe2O3 (iron oxide) and BaCO3 (barium carbonate) or SrCO3 (strontium carbonate). These magnets are formed by powder metallurgy. They are two types of magnet: The isotropic magnet, molded in the absence of magnetic field and the anisotropic magnet, which have outstanding properties in the direction of the field. Because the properties listed in underneath table change somewhat with the shape and size of the magnet, magnet properties are usually set by consultation with the customers. Ask us any time for advice on choosing the type of magnet that best satisfy you needs.
