Makers, hobbyists, marine builders, and small-workshop fabricators who need reliable flat stock turn to cupronickel — a copper-nickel alloy engineered for durability in demanding environments.\u003c\/p\u003e\n\u003cp\u003eThese cupronickel sheet panels are composed of a copper-nickel alloy (typically 70–90% Cu, 10–30% Ni), delivering a balance of electrical conductivity, thermal stability, and corrosion resistance. Available in flat panel sizes from 100×100mm (approx. 3.94×3.94 in) to 200×200mm (approx. 7.87×7.87 in), with thickness options ranging from 0.8mm to 3.0mm (approx. 0.031–0.118 in).\u003c\/p\u003e\n\u003cp\u003eTypical applications include DIY electrical shielding panels, marine hardware fabrication, heat exchanger components for small-scale builds, decorative metalwork requiring a silver-toned finish, and custom gasket or spacer blanks for workshop machinery.\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, and light machining.
