These cupronickel sheet metal plates are stocked in a wide range of thicknesses (0.15 mm to 3 mm) and cut sizes, so you can order exactly what your project demands without paying for excess material.\u003c\/p\u003e\n\u003cp\u003eEach panel is a copper-nickel (cupronickel) alloy flat stock, offering a warm silver-gold tone with inherent resistance to moisture and mild chemical exposure. Sheet dimensions range from compact 100 mm × 100 mm squares (approx. 3.9\" × 3.9\") up to 310 mm × 1000 mm strips (approx. 12.2\" × 39.4\"), with thickness options spanning 0.15 mm to 3 mm (approx. 0.006\" to 0.118\").\u003c\/p\u003e\n\u003cp\u003eTypical applications include decorative inlay work and jewellery fabrication, shielding panels in electronics enclosures requiring EMI attenuation, heat-exchanger baffles and marine fittings where salt-air resistance matters, and thin shim stock for precision mechanical assemblies.
