Copper Nickel 7030, often called CuNi 70/30, gets its strength from a specific composition of about 70% copper and 30% nickel, with small but vital additions of iron and manganese. This blend results in pipes with outstanding mechanical properties. They offer excellent tensile strength and superb ductility, allowing them to be easily formed and welded. Most importantly, they possess exceptional resistance to corrosion, especially from seawater, and are highly resistant to biofouling, making them a remarkably durable and long-lasting choice for demanding applications.
