Top 10 Samarium Cobalt (SmCo) Magnet Suppliers

When high-performance magnetic stability is non-negotiable—especially in temperatures exceeding 300°C—Samarium Cobalt (SmCo) magnets are the definitive choice. Unlike Neodymium, SmCo offers exceptional oxidation resistance, making it vital for aerospace, marine, and defense sensors. However, the quality of these rare-earth materials depends heavily on the manufacturer's sintering process. Based on material purity, manufacturing technology, and market reputation, we have compiled the top 10 SmCo magnet suppliers globally.
