Arnold partners with Less Common Metals and Solvay to secure Western-origin rare earths for magnet production across critical industries.
Rochester, NY — Arnold Magnetic Technologies has signed a supply agreement with Less Common Metals (LCM) and Solvay to secure Western-origin rare earth materials for advanced permanent magnets.
The partnership aims to strengthen supply-chain resilience for aerospace, defense, automotive and energy markets by guaranteeing access to high-quality NdPr, dysprosium, terbium and samarium feedstocks and intermediates. Arnold says the deal will provide commercial flexibility for global customers and support its continued delivery of magnetic assemblies, precision components and highly loaded composites used in motors, generators and sensors.
The agreement complements Arnold's ongoing capital investments in Switzerland and expanded manufacturing capabilities in Thailand, positioning the company to scale production across multiple regions. Solvay has also signaled production milestones, with a Neodymium-Praseodymium (NdPr) line commissioned in April 2025 and planned commercial production of dysprosium, terbium and samarium at La Rochelle in 2026.
By coordinating upstream supply from LCM and Solvay with downstream manufacturing, Arnold aims to reduce sourcing risk for mission-critical magnet technologies and support electrification and defense modernization efforts worldwide.
