Copper Nickel (Cu-Ni) Pipes are top-notch alloy pipes celebrated for their remarkable resistance to corrosion, particularly in seawater and marine settings. Made mainly from copper and nickel, this alloy boasts impressive strength, ductility, and resistance to biofouling. These pipes excel in thermal stability and conductivity, making them perfect for heat exchangers, condensers, and piping systems in marine, power generation, and desalination sectors. Their ability to endure brine, saltwater, and acidic conditions guarantees a long lifespan. Plus, they’re easy to fabricate, weld, and maintain, ensuring dependable performance in both industrial and offshore environments.

Copper Nickel Pipes typically consist of copper (70–90%) and nickel (10–30%), with minor additions of iron and manganese to boost corrosion and erosion resistance. The most popular grades are Cu-Ni 90/10 and Cu-Ni 70/30, each striking a balance between strength and corrosion protection. These pipes showcase a tensile strength ranging from 275–400 MPa, yield strength between 105–150 MPa, and an elongation of about 30–40%. They resist stress corrosion, impingement attack, and hydrogen embrittlement exceptionally well, all while maintaining good thermal conductivity and mechanical stability under high temperatures and pressures.
