Makers, hobbyists, marine fabricators, and electronics builders who need reliable flat stock in exact dimensions will find the copper-nickel alloy sheet plate an indispensable material in their workshop.\u003c\/p\u003e\n    \u003cp\u003eEach panel is cut from cupronickel alloy — a copper-nickel blend known for its excellent corrosion resistance and moderate electrical conductivity. Sheets are available in flat panel sizes ranging from 100×100mm (approx. 3.9\"×3.9\") to 150×150mm (approx. 5.9\"×5.9\") and 100×300mm (approx. 3.9\"×11.8\"), with thickness options spanning 0.2mm to 3mm (approx. 0.008\" to 0.118\"). Multi-piece packs of 1, 2, or 4 pieces are offered to match your project scale.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include DIY shielding panels for electronics enclosures, marine hardware fabrication requiring saltwater-resistant flat stock, heat exchanger shim stock for HVAC and plumbing repairs, and decorative metalwork for jewelry-making or craft projects using thin cupronickel foil sheet.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\n    Compatible with standard metalworking tools — tin snips, metal shears, bench vise, and hand files.
