SmCo24 Samarium Cobalt Magnets

SmCo24 samarium cobalt magnets are high-performance permanent magnets available in both SmCo 1:5 (SmCo₅) and Sm₂Co₁₇ (2:17) material systems. The SmCo24 family includes standard and high-coercivity 1:5 configurations, an LT variant, and multiple 2:17 grade variants, each offering different magnetic properties and temperature-performance characteristics. The Samarium Magnet Company manufactures and supplies custom SmCo24 magnets for applications requiring reliable magnetic performance, including aerospace, defense, motors, generators, sensors, oil and gas, energy, and industrial systems. The table below outlines the available grade variants and their key characteristics to help engineers compare remanence (Br), coercivity (Hcb), intrinsic coercivity (Hcj), maximum energy product ((BH)max), and maximum operating temperature. Custom shapes, dimensions, tolerances, and magnetization configurations are available to meet application-specific requirements.
