Cu-Ni 90/10 (C70600)

Cu-Ni 90/10 (C70600)

Copper Nickel 90/10 (C70600) is a highly durable marine alloy containing 90% copper, 10% nickel, with small additions of iron and manganese that significantly improve its resistance to general corrosion, impingement attack, and biofouling. Due to its stable performance in seawater, C70600 is the global standard for marine piping systems, heat exchangers, cooling loops, and seawater intake/outlet lines.

Cu-Ni 90/10 offers exceptional performance because it naturally forms a protective tenacious oxide film, making it highly resistant to corrosion in both flowing and stagnant seawater. The alloy maintains structural integrity even under high velocity, making it ideal for ship systems, desalination plants, oil & gas offshore platforms, and industrial cooling circuits.

Saifex Industries supplies C70600 copper nickel material in multiple forms including tubes, pipes, plates, coils, bars, fittings, and flanges, all conforming to global specifications such as ASTM B466, B111, B122, B151, and MIL-T-16420.

Recognized for its long service life, Cu-Ni 90/10 is heavily used by marine engineers, desalination plant designers, shipbuilders, and offshore EPC contractors across Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, Iraq, and the UAE.
