Cupronickel Sheet Metal Plate Flat Panel Foil Copper Nickel Thickness 0.15mm~3mm

For decorative inlay, jewellery, or shielding foil work, 0.15 mm–0.5 mm is typically sufficient. For structural shims, brackets, or heat-exchanger baffles that need to hold shape under load, 1 mm–3 mm is more appropriate. If you are unsure, order a thinner sample first and test fit before committing to a larger quantity.

No. Cupronickel is a copper-nickel alloy — distinct from both stainless steel (iron-based) and brass (copper-zinc). It shares brass's warm workability but adds nickel's corrosion resistance, making it a common choice for marine hardware, coinage, and EMI shielding where brass would corrode and stainless would be too hard to form.

Yes. Cupronickel alloys are well-regarded for their resistance to seawater corrosion and biofouling. Thinner foil gauges (0.15 mm–0.5 mm) are better suited to enclosure liners or decorative trim, while 1 mm–3 mm plate is more practical for structural marine fittings. No additional protective coating is required for typical marine exposure.

Thin gauges (0.15 mm–0.5 mm) can be cut with heavy-duty scissors or aviation snips. Gauges from 0.8 mm to 2 mm are best handled with a bench shear, angle grinder with a metal-cutting disc, or laser cutter. The 3 mm plate requires a cold saw, angle grinder, or CNC router. Always deburr cut edges with a file or deburring tool.

Yes. Cupronickel solders readily using standard copper-compatible fluxes and 60/40 or lead-free solder. For brazing, use a silver-bearing brazing alloy with an appropriate flux. Clean the surface with fine abrasive paper before joining to ensure good adhesion.

Measure your finished part dimensions and add at least 5–10 mm on each edge for clamping and cutting allowance. Then match to the nearest available sheet size. For small parts, the 100 mm × 100 mm or 100 mm × 200 mm options reduce offcuts. For long strips or continuous runs, the 310 mm × 1000 mm variant offers the best yield per piece.

Yes. The Qty(pcs) variant option lets you select 1, 2, or 4 pieces of the same size and thickness combination in a single order, which is useful for batch fabrication or keeping spares on hand.
