Superior Alloy for Marine and Industrial Performance

The ASTM B 111 C 71500 Copper Nickel alloy is optimized for challenging environments. Its unique 70/30 copper-nickel composition, combined with iron, grants it formidable strength, superior corrosion resistance in saltwater, and reliability under high temperatures (up to 400C). Used extensively in heat exchangers, condensers, and marine hardware, this material excels in offshore and coastal applications, minimizing maintenance and prolonging equipment life.

Custom Manufacturing and Precision Engineering

Whether you require seamless or welded tubes, this alloy is fabricated to meet precise customer specifications. Available in various diameters (6.35 mm to 254 mm), lengths up to 6 meters, and wall thicknesses from 0.7 mm to 10 mm, it is engineered through cold drawing and annealing processes, ensuring dimensional accuracy and a polished finish. Packing options include plastic caps, wooden boxes, or bundles to preserve quality during transit.

FAQs of ASTM B 111 C 71500 70/30 Copper Nickel:

Q: How is ASTM B 111 C 71500 (70/30 Copper Nickel) utilized in marine applications?

A: This grade is highly favored for marine hardware, heat exchangers, and offshore oil rig components because of its exceptional resistance to seawater corrosion and its structural stability at temperatures up to 400C.

Q: What manufacturing processes are used for producing these copper nickel tubes?

A: The tubes are made using cold drawn and annealed techniques, which ensure dimensional precision, superior surface finish, and enhanced mechanical properties. Both seamless and welded options are available.

Q: When should I consider using C 71500 70/30 Copper Nickel over other alloys?

A: Choose this alloy when you require excellent corrosion resistance in harsh environments, robust mechanical strength, and reliability at elevated temperatures, particularly in heat exchangers, condensers, and marine installations.

Q: Where are ASTM B 111 C 71500 copper nickel tubes typically supplied from?

A: These tubes are manufactured, exported, and supplied from India, with packaging options to ensure safe delivery, including plastic caps, bundled packing, or wooden boxes.

Q: What are the benefits of using seamless versus welded tubes for my application?

A: Seamless tubes offer uniform strength and preferred structural integrity for high-pressure or critical applications. Welded tubes may be suited to standard requirements where cost efficiency is key.

Q: How does the materials composition impact its performance in demanding environments?

A: The 70% copper and 30% nickel blend, with added iron, dramatically increases corrosion resistance, especially in seawater, while providing substantial strength and durability for high-pressure and temperature conditions.
