Home > Copper Nickel > Copper Nickel Pipes
Copper Nickel pipes are top-notch alloy pipes crafted from a blend of copper and nickel, usually in ratios like 70/30 or 90/10. These pipes are known for their outstanding resistance to corrosion, especially in seawater and other harsh environments, while also providing great thermal and electrical conductivity. Their ability to resist biofouling, erosion, and stress corrosion cracking makes them perfect for marine, offshore, and chemical processing uses.
Typically, Copper Nickel pipes consist of 70–90% copper and 10–30% nickel, with a dash of iron and manganese added to boost strength and corrosion resistance. They offer impressive tensile strength and durability, all while remaining flexible enough for easy fabrication and installation. These pipes can handle high pressures and temperatures, as well as constant exposure to seawater, without significant wear and tear.
