What is a C70600 copper nickel tube?
C70600 90/10 copper-nickel alloy (also known as copper-nickel alloy) is an alloy containing 90% copper and 10% nickel. C70600 90/10 is known for its excellent bending properties, machinability, and low macro-fouling deposition rate. GNEE supplies various specifications of C70600 90/10 alloy products, including plates, bars, pipes, fittings, and flanges.

FAQ
What is the typical lifespan of a C70600 seawater system?
With proper design, installation, and maintenance, C70600 systems can have a service life exceeding 40 years.
How does it handle polluted seawater?
It performs well, but performance can be degraded in waters with high levels of sulfide pollution, which can disrupt the formation of the protective oxide film.
Can it be brazed or soldered?
Yes, common brazing and soldering techniques can be used. Ensure fluxes are free of compounds that could cause corrosion.
What is the cost comparison with stainless steel?
While initial material cost may be higher than standard stainless steels (e.g., 304, 316), its superior long-term performance and lower life-cycle cost in seawater often make it more economical.
Where is C70600 most commonly used?
It is the standard material for:
Seawater piping systems on ships and offshore platforms
Condenser and heat exchanger tubes
Desalination plant components
Marine hardware and freshwater systems
