Cu-Ni 90/10 Pipes & Tubes

One of the most valuable characteristics of Copper Nickel 90/10 Pipes & Tubes is their superior mechanical properties combined with excellent weldability and formability. These tubes are commonly used in heat exchangers, condensers, seawater piping, and cooling systems due to their ability to withstand continuous exposure to brackish water and seawater without significant degradation. Their thermal stability ensures efficient heat transfer, which is crucial in power plants and petrochemical facilities. In addition, they perform reliably in cryogenic as well as high-temperature environments, offering versatility across a wide range of industries.

At Neonox Overseas, our Cu-Ni 90/10 Pipes & Tubes are manufactured in compliance with international standards such as ASTM B466, ASTM B467, ASME SB466, and SB467, ensuring global quality benchmarks. We supply these pipes in multiple forms including seamless, welded, ERW, and fabricated types to meet diverse project requirements. The outer diameter ranges from 6 mm to 219 mm, with wall thicknesses from 0.5 mm to 20 mm, and lengths up to 12 meters or custom cut sizes. This flexibility ensures compatibility with a wide range of applications, from small-scale installations to large-scale industrial projects.

In terms of mechanical properties, Cu-Ni 90/10 exhibits a tensile strength of 275 MPa, yield strength of 105 MPa, and elongation of 30%, making it strong yet ductile. With a melting point of around 1100–1145 °C and density of 8.9 g/cm³, it offers both thermal and structural stability. The alloy also demonstrates excellent resistance to hydrogen embrittlement and stress corrosion cracking, which are common concerns in harsh industrial conditions.

Neonox Overseas offers Copper Nickel 90/10 Pipes & Tubes in annealed, pickled, and bright-annealed finishes, ensuring both functional and aesthetic value. These pipes are extensively used in oil refineries, power plants, shipbuilding, desalination, offshore engineering, and chemical industries. Whether for seawater cooling lines, ballast systems, hydraulic lines, or condenser tubing, Cu-Ni 90/10 remains one of the most trusted materials for long-term performance.
