Sintered magnets are high cost-performance magnets made mostly from ferric oxide (Fe2O3), barium carbonate (BaCO3) and strontium carbonate (SrCO3), and produced by powder metallurgy. Magnets can be classified according to their properties as shown in the magnetic property table. Isotropic magnets are press formed in the absence of a magnetic field, while anisotropic (dry and wet pressing) magnets are press formed in a magnetic field to provide direction.
The high coercivity of sintered magnets, which is their main feature, makes them insusceptible to external magnetic fields and self-demagnetization action, and enables them to be shaped in flat and other complex shapes. We also provide polar anisotropic and radial magnets as needed.
