Technical Overview of Cu-Ni 90/10 Alloy

The Copper Nickel 90/10 alloy (UNS C70600 / DIN 2.0872) is a wrought, corrosion-resistant material known for its exceptional ductility, high impact strength, and low-temperature performance. With a balanced chemical composition, this alloy offers a unique combination of mechanical strength and resistance to seawater-induced corrosion, including pitting and stress corrosion cracking. Its inherent resistance to biofouling significantly reduces maintenance in marine environments, making it a go-to material for long-term underwater usage.

The alloy supports excellent weldability and fabricability, allowing it to be easily bent, flared, or joined using standard welding methods. It meets rigorous industry specifications including ASTM B466/B467 and ASME SB111/SB466, making it suitable for seamless, welded, and ERW pipe forms. The antimicrobial properties of Cu-Ni 90/10 also make it an effective choice for applications requiring bacterial control, with the material shown to eliminate 99% of harmful microbes within hours of contact.

Its thermal stability, combined with its tolerance to elevated flow velocities, enables these pipes and tubes to function reliably under both cryogenic and high-pressure conditions. This makes Cu-Ni 90/10 a technically sound option for industries operating in extreme or fluctuating environments.

Applications & Industry Use

90/10 Copper Nickel Pipes & Tubes are widely utilized in marine, offshore, power generation, and chemical processing industries for its durability and wearing of high pressure. In marine applications, they serve in the fabrication of seawater cooling systems, desalination units, bilge and ballast piping, and marine hardware such as valves, pumps, and condensers. Their exceptional corrosion resistance to brine and saline atmospheres makes them indispensable in shipbuilding and coastal infrastructure.

In industrial environments, they are used in heat exchangers, pressure vessels, and condenser tubes where stable thermal transfer and corrosion protection are critical. The alloy’s non-sparking and non-magnetic properties further extend its application into safety-sensitive zones. In addition, the natural antimicrobial properties of 90/10 and 70/10 Copper Nickel Pipes & Tubes make it increasingly valuable in environments where cleanliness is critical, including medical facilities, food production units, and drinking water systems—such as hospital pipelines, kitchen infrastructure, and sanitary water supply lines.

From manufacturing to final deployment, these pipes and tubes are engineered for longevity and consistent performance, offering cost-effective solutions across a wide range of sectors. Their adaptability, combined with proven reliability, has made them a material of choice in multiple global industrial projects.
