Industrial context.
Neodymium is used alongside iron and boron to make high-strength permanent magnets. Commercial supply can be discussed as oxide, metal, NdPr blend, alloy or a finished magnet. Ask which form is being quoted.
Questions for a supplier.
For a motor programme, ask for the magnet grade, geometry, thermal envelope, corrosion protection and source traceability. A quote for oxide alone does not qualify a finished part.
