Copper Nickel 70/30 Pipes consist of roughly 70% copper and 30% nickel, together with minor quantities of iron and manganese that enhance their strength, corrosion resistance, and overall stability. These pipes offer remarkable mechanical properties, such as dependable tensile strength, sturdy yield strength, and excellent ductility, enabling them to work effectively under high pressure and fluctuating temperatures. They resist seawater corrosion, erosion, stress corrosion cracking, and biofouling, which makes them well-suited for long-term use in tough environments. The alloy’s durability and thermal stability ensure reliable performance in rigorous industrial and marine applications.
