Hobbyists, makers, and small-shop fabricators working on electrical shielding, heat exchangers, marine hardware, or decorative metalwork need a material that performs reliably across a range of thicknesses without warping or pitting. These copper-nickel alloy sheets are stocked specifically for that gap.\u003c\/p\u003e\n    \u003cp\u003eEach copper-nickel alloy sheet is cut from 18Ni-grade Cu-Ni flat stock. Available panel sizes run from 100×100 mm (approx. 3.9×3.9 in) up to 100×300 mm (approx. 3.9×11.8 in) and 150×150 mm (approx. 5.9×5.9 in), with thickness options spanning 0.2 mm through 3 mm (approx. 0.008–0.118 in). Sheets are supplied in 1-piece or 2-piece quantities depending on the variant selected.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include RF\/EMI shielding enclosures where conductivity and corrosion resistance must coexist, thin shim stock for precision mechanical assemblies, decorative inlay work in woodworking and jewelry, and replacement flat stock for marine or plumbing fittings exposed to moisture. The combination of copper's conductivity and nickel's corrosion resistance makes these sheets a practical choice for copper-nickel alloy sheet applications in both indoor and outdoor environments.\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    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for soldering, brazing, light machining, and bending.
