Diverse Forms of High-Purity Nickel Materials
Nickel 200 (UNS N02200) is a commercially pure nickel alloy with a nickel content exceeding 99.0%. Its excellent corrosion resistance, good mechanical properties, and outstanding machinability make it widely used in various industrial fields. This material can be processed into various forms such as plates, foils, and sheets to meet diverse industry needs.
Product Forms and Specifications
Nickel 200 Plates
Nickel 200 plates typically range in thickness from 0.3mm to 50mm and in width exceeding 2000mm. Surface finishes include hot rolling, cold rolling, and annealing, and different hardness states (soft (M), semi-hard, hard (H)) can be selected according to application requirements. The plates possess good weldability and formability, making them suitable for manufacturing large equipment such as chemical containers, reactors, and heat exchangers.
Nickel 200 Foils
Nickel 200 foils are extremely thin, reaching thicknesses of 0.02mm or even thinner, and widths up to 330mm. The foil is produced using a high-precision cold rolling process, with thickness tolerance controlled within ±0.001mm, high surface smoothness, and a curvature ≤0.5mm/M. The foil possesses excellent conductivity and oxidation resistance, making it particularly suitable for precision applications such as electronic components, battery electrodes, and electromagnetic shielding.
Ni 200 Sheet
Ni 200 sheet is positioned between sheet and foil, with a thickness typically between 0.1mm and 3mm. The sheet exhibits good ductility and processability, and can be processed into various shapes through stamping, shearing, and bending. The sheet is widely used in food processing equipment, electronic instrument parts, and chemical equipment linings.
