High-purity neodymium ingot is refined using vacuum reduction or distillation methods. Each batch is thoroughly tested using GDMS, ICP-MS, and ONH analyzers to verify purity, chemical composition, and trace impurity levels before further processing.
The refined neodymium is hot-forged into billets to refine grain structure and improve workability. Billets are then hot-rolled into intermediate slabs, creating a dense and uniform structure suitable for precision cold rolling.
Slabs are cold-rolled through multiple passes to achieve the required thickness with tight tolerances:
- Foils: as thin as 20 µm
- Sheets: up to 40 mm
Intermediate annealing is performed as needed to relieve internal stress, maintain ductility, and ensure uniform thickness — especially important for ultra-thin foil production.
Rolled material is cut, slit, or trimmed to the specified dimensions with high accuracy. Optional edge deburring and surface polishing are applied to meet applications requiring smooth surfaces and safe handling.
Each foil and sheet is inspected for flatness, dimensional accuracy, and surface quality. Approved materials are ultrasonically cleaned to remove any dust, oil, or other contaminants before packaging.
Finished products are vacuum-sealed in moisture-proof bags and packed in shock-resistant cartons. Each shipment includes a Certificate of Analysis (COA), packing list, and other required documentation.
