What is Copper Nickel Flat Bars?

Our Copper Nickel Flat Bars, often referred to as Cu-Ni or 90/10 alloys, primarily consist of copper with about 10% nickel and small additions of iron and manganese for enhanced strength. This specific composition gives the bars outstanding mechanical properties, including excellent tensile strength and remarkable ductility. They are particularly valued for their exceptional resistance to corrosion, especially in saltwater environments, and their ability to withstand biofouling, making them incredibly tough and long-lasting even under stressful conditions.
