At Nasir Nickel Alloys in Manama, Bahrain, Copper Nickel 90/10 Flanges are designed to provide excellent corrosion resistance, mechanical strength, and long-term reliability for demanding marine, chemical, and industrial applications. Manufactured from a high-quality copper-nickel alloy, these flanges offer superior resistance to seawater, brackish water, and chloride-induced corrosion while maintaining structural integrity under high-pressure conditions. Precision-engineered for leak-proof connections and consistent performance, Copper Nickel 90/10 Flanges are ideal for seawater piping, desalination plants, heat exchangers, and marine systems, providing durable and reliable solutions in aggressive and highly corrosive environments.
Copper Nickel 90/10 Flanges are primarily composed of approximately 90% copper and 10% nickel, with minor iron and manganese additions to enhance strength and corrosion resistance. This composition provides outstanding resistance to seawater, brackish water, and biofouling, as well as excellent pitting and crevice corrosion resistance. Mechanically, these flanges offer good tensile and yield strength, toughness, and fatigue resistance under fluctuating pressures and thermal cycling. With dimensional stability and structural integrity in aggressive marine and industrial environments, Copper Nickel 90/10 Flanges combine corrosion resistance with mechanical durability for reliable long-term performance.
