Recoma sintered samarium cobalt (SmCo) magnets are high-performance permanent magnets designed for demanding applications requiring excellent magnetic properties at elevated temperatures and superior corrosion resistance. The family includes grades such as Recoma 18 through Recoma 35E, with maximum energy products ranging from 135 kJ/m³ to 265 kJ/m³ and residual induction from 0.83 T to 1.19 T. These magnets operate at maximum temperatures up to 350°C, exhibit low reversible temperature coefficients of induction (−0.035%/°C to −0.050%/°C), and do not require protective coatings due to inherent corrosion stability. They are available in axial or transverse magnetization orientations and have a density of approximately 8.3-8.4 g/cm³. Curie temperatures exceed 725°C, and they demonstrate high intrinsic coercivity up to 880 kA/m. The materials are suitable for aerospace, automotive, and chemical industry applications.
Arnold Magnetic Technologies’ industry leading RECOMA Samarium Cobalt (SmCo) magnet materials break the performance barriers of other magnetic components. Offering several operational advantages, our top-of-the-line RECOMA 35E is currently the most power dense samarium cobalt magnet on the market, and is specifically created for the most demanding environments, including high speed (100,000 RPM+), high temperature (above 150°C) and highly corrosive environments, such as aerospace, motorsports, and automotive industries. As the market leader in high performance SmCo, Arnold Magnetic Technologies continues to push the boundaries of magnetic performance, while maintaining an integrated and sophisticated supply chain.
All locations in our RECOMA product’s supply chain are registered with ITAR and can adhere to DFAR clauses.
Arnold’s custom SmCo magnets are made to your specification and project requirements.
