Large Strontium Anisotropic Magnet Ring C8 Grade

Large Strontium Anisotropic Magnet Ring – C8 Grade

Our Large Strontium Anisotropic Magnet Ring (C8 Grade) is a high-performance permanent magnet engineered for demanding industrial applications. Manufactured from strontium ferrite (SrFe₁₂O₁₉) using advanced sintering techniques, this magnet combines excellent magnetic strength, remarkable stability, and outstanding resistance to demagnetization.

The C8 Grade designation signifies a magnet optimized for high coercivity and moderate energy product, making it ideal for motors, generators, automotive sensors, loudspeakers, and magnetic couplings. Thanks to its anisotropic structure, the magnet is oriented during manufacturing to maximize magnetic performance in a specific direction, resulting in significantly higher magnetic output compared to isotropic grades.
