C71500 Copper Nickel Size & Price PDF

Copper-nickel alloys, composed of 70% copper and 30% nickel, are metals with excellent machinability and corrosion resistance. They possess excellent ductility, making them suitable for deep processing. The product grade is C71500, abbreviated as C715, and can be used to manufacture plates, sheets, and tubes.

C71500 Copper Nickel Alloy is typically used in areas where need high temperatures and pressures combined with high velocity and turbulence.

Chemical processing application| condensers and boiler parts, heat exchanger components, process equipment, refrigerators, propeller sleeves, ferrules, heat exchanger tubes, evaporator tubes, distiller tubes, condenser plates, flexible metal hose, pump impellers, welding backing rings, valve bodies and fittings.

Marine applications| salt water flanges, salt water piping, pump bodies and internal parts-sea water, sea water condensers, salt water pipe fittings, water boxes.

Q: How does the cost of C71500 compare to other corrosion-resistant alloys?

A: It is generally more cost-effective than high-nickel alloys like Alloy 400 (Monel) or super duplex stainless steels for long-term service in seawater, considering its lifespan and low maintenance.

Q: How should C71500 pipe be stored to prevent corrosion?

A: Store it in a clean, dry, and well-ventilated area. Avoid contact with carbon steel dust or chips, which can cause embedded iron corrosion (pitting).

Q: What cleaning methods are recommended for C71500 systems?

A: For new systems, a mild acidic clean (e.g., with sulfamic or citric acid) is often used to remove mill scale and promote the formation of a uniform protective film before commissioning. Avoid abrasive cleaners that can damage the surface.

Q: Why is C71500 so resistant to seawater corrosion?

A: It forms a tight, adherent, and protective surface oxide film that is highly resistant to various forms of corrosion, including impingement attack, crevice corrosion, and stress corrosion cracking in marine environments.

Q: Is C71500 resistant to biofouling?

A: While not completely anti-fouling, the corrosion product film on C71500 is less conducive to marine organism attachment than many other metals, and the release of copper ions into the water provides a mild biofouling resistance.
