Sources Sought Rare Earth Magnets

The U.S. Army is conducting market research to identify vendors capable of supplying high‑performance rare‑earth neodymium magnets (Grade N52SH preferred, N42SH acceptable) with triple‑layer Ni‑Cu‑Ni coating for brushless DC motors used in small unmanned aircraft systems. The solicitation is informational only; no contract is guaranteed, and responses are voluntary. Vendors must demonstrate manufacturing capability, supply‑chain transparency, and rigorous quality‑control testing for magnetic properties, coating integrity, and dimensional tolerances. Responses are due by the specified deadline and must include company and capability data in a concise, bullet‑style format. • Required magnet grades: N52SH (preferred) and N42SH (acceptable) with specific magnetic performance thresholds. • Physical dimensions for three motor sizes (3115, 2807, 2407) with exact outer/inner diameters, arc angles, heights, and thicknesses. • Quantity: 14 magnets per motor type (total 42 per grade) and potential for additional variations. • Vendors must provide detailed supply‑chain documentation from raw material extraction through final magnet production, as well as internal testing methods for magnetic and coating properties.
