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 cupro nickel metal?

Cupronickel (also known as copper-nickel) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Despite its high copper content, cupronickel is silver in colour.

What is Ni Cu alloy?

Cu-Ni alloys are alloys of copper (base metal with the largest individual content) and nickel with or without other elements, whereby the zinc content may not be more than 1%. When other elements are present, nickel has the largest individual content after copper, compared with each other element.

Is cupronickel magnetic?

The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals aren’t magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.

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EEMUA 234 is a new publication that combines and updates the content of EEMUA 144, 145 and 146, which have now been withdrawn.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.

Why is Monel good for shipbuilding?

Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel was created in 1905 by Robert Crooks Stanley, who at the time worked the International Nickel Company (Inco).

Is Monel better than stainless steel?

Monel is very, very corrosion resistant, but is typically much more expensive than even 316L stainless. Monel is a superior fuel tank material, hard to imagine anything better. If you could afford it, it would probably be great for water tanks, too, but at the high end these are usually 316L stainless.

What is the commercial name of 60 Ni 40 Cu?

Leaded Brass 60/40

What kind of corrosion does C70600 copper have?

The C70600 (90/10) copper nickel alloys have great resistance to sea water corrosion due to the presence of significant amounts of manganese and iron.

What is the annealing temperature of UNS C70600 copper alloy?

The annealing temperature of UNS C70600 copper nickel alloy is between 593 and 816°C (1100 and 1500°F). Applications. UNS C70600 copper nickel alloy is primarily used for seawater service as forged and machined valve and pump components, fittings and hardware.

When to use UNS C70600 copper seamless tubes?

Suitable for high temperature service. UNS C70600 copper nickel alloys are used in areas where stainless steel cannot be used due to chloride stress-corrosion cracking (CSCC) and in other parts requiring high levels of corrosion resistance.

Why is C706 also known as copper nickel 90 / 10?

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.
