Saifex Industries supplies premium Cu-Ni 90/10 (C70600), the industry-standard copper nickel alloy known for its exceptional corrosion resistance, biofouling resistance, and durability in seawater environments. With 90% copper and 10% nickel, this alloy provides outstanding protection against seawater corrosion, stress corrosion cracking, pitting, and erosion, making it the most widely used material for seawater piping systems globally.
We supply Cu-Ni 90/10 tubes, pipes, sheets, plates, coils, fittings, and custom marine components across Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, Iraq, and the United Arab Emirates.
Excellent resistance to seawater corrosion and marine fouling
Performs exceptionally in brackish water, saline environments & offshore systems
Resistant to stress corrosion cracking, pitting, and crevice attack
Good fabrication, weldability, and formability
Preferred alloy for marine piping, heat exchangers, condensers & coolers
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.
