Copper Nickel Sheets are one of the most versatile and highly demanded non-ferrous products in the global market due to their exceptional combination of strength, corrosion resistance, and thermal stability. At Neonox Overseas, we are recognized as a leading exporter, stockist, and supplier of high-quality Copper Nickel Sheets manufactured in compliance with international standards like ASTM, ASME, and DIN. These sheets are widely used in marine engineering, power plants, desalination units, heat exchangers, condensers, and offshore oil and gas industries, where resistance to seawater and biofouling is critical.
Copper Nickel (commonly known as Cu-Ni) alloys are primarily available in two widely used compositions – 90/10 (C70600) and 70/30 (C71500). Copper Nickel 90/10 Sheets contain 90% copper and 10% nickel, with small additions of iron and manganese to enhance corrosion resistance. These sheets are well-suited for moderate seawater environments, piping systems, ship hulls, and condenser tubes. On the other hand, Copper Nickel 70/30 Sheets consist of 70% copper and 30% nickel, providing superior mechanical strength and greater resistance to erosion, making them the preferred choice for more demanding marine and industrial applications.
Our Copper Nickel Sheets are available in a wide range of thicknesses, sizes, and finishes, including hot-rolled, cold-rolled, polished, and custom-cut dimensions. These sheets exhibit excellent ductility, toughness, and weldability, allowing them to be easily fabricated into complex shapes and structures. With outstanding resistance to stress corrosion cracking, hydrogen embrittlement, and scaling at elevated temperatures, Copper Nickel Sheets ensure long-lasting performance even in the harshest operating conditions.
In addition to the commonly used grades, Neonox Overseas also supplies Cu-Ni Sheets in customized alloys and tempers as per client requirements. Our inventory includes annealed, hardened, and precision-cut Copper Nickel Sheets to cater to diverse industries such as shipbuilding, petrochemical processing, offshore drilling platforms, power generation, and chemical industries.
We take pride in offering Copper Nickel Sheets that are thoroughly tested for mechanical properties, dimensional accuracy, and chemical composition. With our strong distribution network and global export capabilities, we guarantee timely delivery of Copper Nickel Sheets to clients across Europe, the Middle East, Asia, Africa, and the Americas.
Whether you require Copper Nickel 90/10 Sheets for shipbuilding or Copper Nickel 70/30 Sheets for high-strength seawater applications, Neonox Overseas is your trusted partner. Our commitment to quality, reliability, and customer satisfaction ensures that every Copper Nickel Sheet supplied by us meets the highest industry standards and provides unmatched value to our clients.
