Brazil’s 2026 Rare Earth Policy: Impact on NdFeB Magnets
Brazil’s 2026 rare earth policy raises new supply chain questions. Explore the impact on NdFeB magnet sourcing, material origins, and Vietnam manufacturing.
How to Calculate Magnet Strength: From Br to Surface Gauss Measurement
Magnet strength is not determined by grade alone. Learn how Br, magnet size, measurement distance, and Center vs. Maximum Gauss affect the Surface Gauss of a finished magnet.
How to Manage NdFeB Magnet Supply Chain Risks: A Diversified Sourcing Guide for Procurement Teams
More than 90% of global rare-earth refining and magnet production capacity is concentrated in China. Over the past year, repeated changes in tariffs and export controls have turned supply chain diversification from a strategic concept into a practical risk-management priority for procurement teams.
U.S. Defense Supply Chain Shake-Up: Rare Earth Magnets Face a New Traceability Test
Policy pressure on the U.S. rare earth and magnet supply chain is rising. On July 20, 2026, the White House issued an executive order requiring critical materials and components used in defense procurement to shift more clearly toward U.S. domestic and allied sources. Some waiver mechanisms will also be tightened starting January 1, 2027.
Industry Insight | Arafura's India Offtake Agreement Signals a New Phase in the Global Rare Earth Magnet Supply Chain
Australian rare earth developer Arafura Rare Earths has announced a binding offtake term sheet with a special purpose vehicle (SPV) established by an Indian industrial group. Under the agreement, the Nolans Project will supply up to 500 tonnes per year of rare earth materials, including NdPr (Neodymium-Praseodymium), Dysprosium (Dy), and Terbium (Tb), for an initial five-year period with an option to extend for an additional two years.
China Locks Down Rare-Earth Technology as Lynas Moves Into Malaysian Magnet Plant: Global NdFeB Supply Chain Accelerates Restructuring
China's export controls have expanded from rare-earth raw materials to magnet manufacturing technology. Meanwhile, Lynas and South Korea's JS Link are advancing a 3,000-ton-per-year NdFeB magnet plant in Malaysia, signaling that the non-China rare-earth supply chain is moving from raw materials into magnet manufacturing.
NdFeB Magnet Rust Prevention: Coating Thickness and Salt Spray Hours Explained
NdFeB magnets are powerful but highly vulnerable to oxidation from moisture and salt. This guide covers zinc, Ni-Cu-Ni, and epoxy coating thickness, salt spray hours, and application scenarios.
