Copper Nickel Alloy Low Fin Tube , ASTM B111 C71640 , Cu70Ni30

ASTM B111 C71640 (Cu70Ni30) Copper Nickel Alloy offer a unique combination of enhanced heat transfer efficiency and superior resistance to corrosion. These tubes are specifically designed for use in harsh marine and industrial environments, providing reliable performance and longevity. Whether in marine, desalination, power generation, or chemical processing applications, these low fin tubes deliver a compact, cost-effective, and durable solution for modern heat exchanger challenges.

C71640 Copper Nickel Alloy Low Fin Tube improves the thermal performance, which fins create turbulence in the fluid flow, enhancing the convective heat transfer coefficient and overall thermal efficiency. And the C71640 / Cu70Ni30 alloy offers excellent resistance to seawater corrosion, making these tubes ideal for marine and coastal applications.
