Arnold Magnetic Technologies announces landmark supply agreement with Less Common Metals and Solvay

Arnold Magnetic Technologies Corporation, a subsidiary of Compass Diversified and leading global manufacturer of high-performance magnets and precision components, announced a landmark supply agreement with Less Common Metals and Solvay to secure a reliable source of high-quality, Western-origin rare earth materials to produce advanced permanent magnets.

This strategic partnership demonstrates Arnold’s commitment to strengthening the rare earth supply chain and ensuring long-term stability for customers in aerospace, defense, automotive, and energy markets. By bolstering access to critical materials, Arnold continues to deliver breakthrough solutions and maintain industry leadership in magnetic assemblies and precision components.

“As market demand accelerates for sustainable, Western-sourced magnet materials, Arnold is taking decisive action to guarantee supply and provide commercial flexibility for our customers,” says Aaron Williams, chief commercial officer of Arnold Magnetic Technologies. “This partnership further reinforces our ability to serve global markets with next-generation magnetic solutions.”

“We're very pleased to partner with LCM and Arnold Magnetic Technologies to provide essential resources for high-performance applications, particularly in the strategic domain of the European Aerospace Industry,” says An Nuyttens, president of GBU Special Chem at Solvay. This collaboration is part of Solvay’s broader commitment to sustainable and secure rare earth supply chains, both in Europe and abroad.

These supply chain developments complement Arnold’s ongoing capital investments in Switzerland and expanded manufacturing capabilities in Thailand, positioning the company to serve multiple markets worldwide in a commercially competitive fashion.

The news follows Solvay’s recent announcements regarding the commissioning in April 2025 of a production line for Neodymium-Praseodymium (NdPr) for magnets and the launch of the commercial production of Dysprosium (Dy), Terbium (Tb) and Samarium (Sm) as of 2026 on its historical flagship site of La Rochelle, France.
