What is a C70600 copper nickel tube?
GNEE maintains a large stock of C706 copper-nickel alloy, including bars, plates, pipes, fittings, and flanges. C706, also known as 90/10 copper-nickel alloy due to its 10% nickel content, conforms to ASTM B466, ASME SB466, and ASTM B111 standards. C706 is renowned for its moderate strength, good weldability, and formability. Furthermore, due to the addition of appropriate amounts of iron and manganese, the 90/10 alloy exhibits excellent corrosion resistance, stress cracking resistance, and resistance to erosion and impact from high-speed turbulent flows (including bubbles and silt). If you cannot find a material that perfectly meets your requirements, please call or request a quote; we are happy to assist you.

FAQ
How does C70600 compare to C71500 (70-30 CuNi)?
C70600 is more cost-effective with good all-around corrosion resistance. C71500 offers superior strength and better resistance to higher velocity seawater and erosion-corrosion, but at a higher cost.
Why is C70600 resistant to seawater?
It forms a thin, adherent, and protective surface oxide film that is stable in seawater. This film is a complex mixture of copper oxide and nickel and iron oxides, which heals itself if damaged.
Can C70600 withstand freezing temperatures?
Yes, it retains excellent toughness and ductility at cryogenic temperatures, making it suitable for LNG and other low-temperature applications.
How does its biofouling resistance work?
The alloy slowly releases copper ions into the water, which are toxic to marine organisms like barnacles and mussels, preventing them from attaching firmly to the surface.
What are the velocity limitations for seawater in C70600 pipes?
For continuous service, a maximum seawater velocity of 3-3.5 m/s (10-12 ft/s) is generally recommended to prevent erosion-corrosion.
