N48SH neodymium magnets are high-performance sintered neodymium-iron-boron (NdFeB) permanent magnets that combine high magnetic energy with enhanced resistance to demagnetization at elevated temperatures. The N48 designation identifies the magnet's energy-product grade, while SH indicates a high-coercivity class intended for applications requiring improved resistance to irreversible demagnetization under demanding operating conditions. The Samarium Magnet Company supplies custom N48SH magnets formulated with dysprosium (Dy) and terbium (Tb), heavy rare earth elements used to enhance intrinsic coercivity and support magnetic stability at elevated temperatures. These magnets are suitable for engineering applications such as electric motors, generators, sensors, aerospace systems, defense equipment, and industrial machinery where both magnetic output and thermal performance matter. We can work with your specified dimensions, shapes, coatings, tolerances, and magnetization direction to meet your design requirements. Contact The Samarium Magnet Company to discuss your N48SH specifications, operating conditions, and custom magnet requirements.
Did you know? N45SH neodymium magnets belong to the Nd2Fe14B family of permanent magnets, known for delivering high magnetic energy in a compact size. The “N45” designation indicates a nominal maximum energy product grade of approximately 45 MGOe, while “SH” identifies a high-coercivity class designed for applications requiring improved resistance to demagnetization at elevated temperatures compared with standard N-grade magnets.
