Ι What Are Ferrite Block Magnets?
Ferrite magnets, also known as ceramic magnets or hard ferrites, are non-metallic permanent magnets made from Iron Oxide (Fe2O3) together with Barium Carbonate (BaCO3) or Strontium Carbonate (SrCO3) as the main raw materials. These magnets are manufactured through a powder metallurgy process and are valued for their low cost, moderate magnetic properties, and high resistance to corrosion, making them ideal for applications where both durability and cost-effectiveness are important.
Ferrite block magnets are one of the simplest shapes in this family, characterized by their rectangular or cuboid form. They are typically specified by length, width, and height, with the magnetization direction generally aligned with the thinnest dimension. Ferrite block magnets are widely used in applications such as magnetic separators and holding systems, including magnetic door catches.
