Samarium cobalt magnets are made from a blend of samarium (Sm) and cobalt (Co), and are typically produced in grades ranging from 18 to 32. Known for their ability to withstand high operating temperatures (above 180 °C) and resist opposing demagnetizing forces, SmCo magnets are a reliable choice in demanding applications.

At SuperMagnetMan, we offer a wide selection of SmCo magnets—powerful rare earth magnets prized for their temperature stability, corrosion resistance, and long-term reliability. These properties make them well-suited for medical devices, high-temperature motors, and harsh industrial environments.

Our SmCo magnets are available in a variety of shapes, sizes and grades to meet precise performance requirements. Below are some of our most popular product categories to help you find the right fit quickly:

SmCo magnets (grades 18–32) withstand high temperatures (above 180 °C) and resist demagnetization—ideal for medical devices, high-temperature motors, and harsh environments. Explore the categories below to quickly find the right fit for prototyping, testing, or production.
