Ceramic magnets, also known as sintered ferrite magnets, are crafted by combining Barium or Strontium Ferrite with Iron Oxide. These magnets deliver a medium-strength magnetic field while exhibiting high resistance to demagnetization. Offering an affordable solution, ceramic magnets find wide-ranging applications in magnetic components.
Ceramic magnets can be manufactured with either isotropic or anisotropic properties. The most commonly produced grades include C1, C5, and C8. While C1 magnets possess lower energy, they are isotropic, meaning they can be magnetized in any direction. It’s worth noting that parts magnetized through the pressing dimension typically yield slightly stronger magnetic strength.
On the other hand, grades 5 and 8 ceramic magnets are anisotropic and require magnetization in the direction of manufacture. These grades exhibit higher magnetic force compared to C1 materials. Additionally, ceramic magnets boast excellent corrosion resistance and can operate effectively within a temperature range of -40°C to +250°C.
In summary, ceramic magnets offer a cost-effective solution for diverse applications. Their medium strength, resistance to demagnetization, and corrosion resistance make them a reliable choice across various industries. Whether it’s isotropic or anisotropic grades, ceramic magnets deliver the desired magnetic properties while maintaining affordability and operational stability within specified temperature ranges.
