Conference: 40+ Magnet Research Studies Targeting Heavy Rare Earth Reduction, Advanced Motors and AI

Highlights

• Over 40 presentations at China's Suzhou magnet forum covered NdFeB, SmCo, additive manufacturing, and AI-assisted magnet design
• Grain-boundary diffusion research aims to cut dysprosium and terbium usage per kilogram of finished magnet without sacrificing coercivity
• Cerium and lanthanum substitution for neodymium shows promise in select applications but involves trade-offs in strength and temperature performance
• Samarium-cobalt research targets high-temperature aerospace and defense magnets, signaling China's strategy extends well beyond NdFeB
• Western supply chains face compounding risk as China advances material efficiency and manufacturing yields simultaneously across multiple magnet types
