Samarium Cobalt Magnets are a type of Rare Earth Magnet, which are composed of samarium and cobalt and are characterized by their high resistance to demagnetization. These magnets are used across a wide range of applications, including spaceflight, national defense, microwave, and sensors. Samarium Cobalt Magnets are available in a variety of grades, including YXG-26H, YXG-30H, YXG-28, YXG-30, and YXG-32. They are available both uncoated, as well as custom-coated to meet your specific requirements. Samarium Cobalt Magnets can be magnetized through axial, thickness or customized polarization to ensure you receive the exact performance you need. With operating temperatures ranging from 250 to 500°C, Samarium Cobalt Magnets are sure to meet your application's requirements.
