Permag Secures Western SmCo Supply Triangle

Permag has formed a strategic supply agreement with Solvay and Less Common Metals (LCM) to strengthen Western production of Samarium Cobalt (SmCo) magnets.

The three-way arrangement links Solvay’s Samarium oxide separation, LCM’s alloy metallization, and Permag’s precision magnet manufacturing, creating one of the few non-Chinese SmCo supply chains. The magnets serve defense, aerospace, sensors, robotics and high-temperature applications where SmCo’s thermal stability and magnetic performance are required.

The deal is sized to meet anticipated demand for roughly 3–5 years, providing short-term assurance for mission-critical programs and highlighting a tangible step toward supply chain resilience. At the same time, the partnership exposes how thin Western capacity remains: Solvay and LCM operate at a fraction of Chinese scale, and limited throughput, pricing volatility, or a single production outage could ripple through defense and aerospace supply lines.

Industry observers call the move a strategically important incremental gain - meaningful for near-term security, but a reminder that sustained upstream and midstream investment is required to reduce long-term reliance on dominant global suppliers.
