Supplier's Category: All Rare Earth & Magnetic Materials: Neodymium magnets and soft magnetics
Rare earth and magnetic materials — neodymium magnets, soft magnetic alloys — provide the magnetic properties behind motors, sensors, and actuators. Sourcing is shaped by geopolitical supply concentration as much as by magnetic grade specification.
Supply chain risk is unusually concentrated in this material category, so sourcing resilience deserves as much attention as the magnetic grade itself.
- Confirm magnetic grade (e.g., N42, N52) and temperature coefficient match your application’s operating range
- Ask about supply chain origin and second-source availability, given rare earth supply concentration
- Check coating and corrosion protection, since neodymium magnets corrode readily uncoated
Related terms: neodymium (NdFeB) magnets, samarium cobalt magnets, soft magnetic alloys, magnetic grade specification (N35-N52), temperature coefficient of magnets, magnet coating (nickel, epoxy), rare earth supply chain
