High-purity samarium ingots are produced using vacuum induction melting (VIM) or electron beam melting (EBM). Each batch is thoroughly tested using GDMS, ICP-MS, and ONH analyzers to confirm purity, chemical composition, and trace impurity levels before processing.
The solid ingots are hot-forged into billets, refining grain structure and improving workability. Billets are then hot-rolled into intermediate slabs, providing a dense and uniform structure ready for precision 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 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 dimensional accuracy, flatness, and surface quality. Approved items are ultrasonically cleaned to remove dust, oil, and other contaminants.
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.
