C71500 – CuNi 70-30% – CuNi30Mn1Fe

C71500 copper nickel tubes, composed of 70% copper and 30% nickel, offer the highest corrosion and impingement resistance of any copper-based alloy. Designed for severe marine and industrial environments, this alloy delivers unmatched durability and long-term performance even under the most aggressive conditions.

Known for their resistance to acidic waters, high-velocity seawater, and stress corrosion, CuNi 70/30 tubes are the preferred material in systems where reliability, longevity, and minimal maintenance are essential.

C71500 copper nickel tubes are commonly used in:

• Heat exchangers, condensers, and cooling systems in demanding marine or industrial settings
  

• Desalination plants and high-salinity water treatment systems
  

• Marine piping systems for shipboard cooling, bilge, and ballast water
  

• Chemical processing lines exposed to corrosive fluids and high pressure
  

• Offshore oil & gas platforms operating in harsh coastal conditions

• Thermal systems with high turbulence or flow-induced stress

• Maximum corrosion and erosion resistance: withstands aggressive waters, acids, and high-velocity flow better than any other copper alloy.

• Exceptional durability under extreme conditions: ideal for high-pressure, high-temperature, and chemically aggressive environments.

• Outstanding impingement resistance: prevents wall thinning and wear in turbulent, fast-flowing systems.

• Biofouling and scaling resistance: reduces maintenance in long-term seawater exposure.

• Efficient thermal conductivity: ensures optimal performance in demanding heat transfer systems.

• Industry standard compliance: manufactured to meet ASTM B111 and other global engineering specifications.
