    Samarium cobalt magnets (SmCo) have high magnetic performance, low temperature coefficient, high operating temperature (>150°C), and excellent corrosion and oxidation resistance, making them widely used in aerospace, microwave devices, communication systems, medical equipment, sensors, and motors.

    Hangzhou Permanent Magnet Group (HPMG), a major global manufacturer of SmCo magnets, offers a full range of products including high-performance, low-temperature-coefficient, and high-temperature-resistant variants. Our independently developed 35H series samarium cobalt magnets are currently the industry-leading products.

    Detailed product parameters can be downloaded from the end of this page or from the download section.




    HPMG has independently developed 35H SmCo magnets, which are at the forefront of the industry




    HPMG can mass produce special SmCo magnets with high operating temperature (550°C) and low temperature coefficient
