What is C70600?
CuNi 90/10 (C70600 & C7060X) is a Copper Nickel Iron alloy with a small content of manganese which allows excellent resistance to sea- and brakish water. Of all commercial coper alloys, CuNi 70/30 (C71500) offers the best resistance to aqueous corrosion.
What is 90 10 copper nickel?
Nickel C706
Copper Nickel C706 is also known as Copper Nickel 90/10 because it is made up of 10% nickel or as ASTM B466 and ASME SB466. C706 is known for its moderate strength, weldability, and formability.
Does cupro nickel rust?
Copper nickel alloys, also known as Cu-Ni, offers excellent corrosion resistance, especially in marine salt water environments. These various alloys also have important additions of iron and manganese, which are necessary to maintain good corrosion resistance in the harsh environments.
What is the density of cupronickel?

What is Inconel made out of?
Unlike other metal alloys in the family, Inconel® 690 is made of high-chromium and nickel. The use of high-chromium makes this particular variant of the metal alloy highly resistant to the corrosive conditions synonymous with aqueous environments.
What is Eemua 234?
EEMUA 234 is a new publication that combines and updates the content of EEMUA 144, 145 and 146, which have now been withdrawn. Bringing everything together into one publication means the information is more accessible to the user. The new Publication is available to purchase directly from EEMUA through the online Shop.
Is cupro nickel better than copper?
For most the standard heat exchanger material is copper and these are suitable for any well-balanced pool and spa water. For salt-water pools the thicker copper exchanger is better than the basic, but the cupro-nickel version is specifically made for this salt-water residential pool application.
Which metal is highly resistant to corrosion by sea water?
Aluminium Bronze
One alloy, which is particularly resistant to seawater and generally very resistant to corrosion is Aluminium Bronze. Aluminium Bronze alloys consist mainly of copper to which 9-14% aluminium is added.
Is copper a white?
Yes, although its not actually copper but rather an alloy of copper called Cupronickel. I am in the copper industry for almost 50 years and never came across this term. When tarnished or oxidized, copper can be blue, green, red, or black.
What is Monel metal made of?
Monel, any of a group of nickel-copper alloys, first developed in 1905, containing about 66 percent nickel and 31.5 percent copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater.
What can UNS C70600 copper alloy be used for?
UNS C70600 copper nickel alloy is primarily used for seawater service as forged and machined valve and pump components, fittings and hardware. This alloy is also used in applications requiring high corrosion resistance and where chloride stress-corrosion cracking precaution prevents usage of stainless steels.
What is the annealing temperature of UNS C70600?
The annealing temperature of UNS C70600 copper nickel alloy is between 593 and 816°C (1100 and 1500°F). UNS C70600 copper nickel alloy is primarily used for seawater service as forged and machined valve and pump components, fittings and hardware.
What are the uses of C706 copper fittings?
They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance. Some of the primary uses for C706 include copper nickel fittings (CuNi Fittings) as well as condensers and exchanger shells.
How is UNS C70600 used in marine engineering?
Over several decades, many thousand of tons of the copper-nickel alloy UNS C70600 have been used as a seawater piping material in marine engineering.
