At Nasir Nickel Alloys in Manama, Bahrain, Copper Nickel 70/30 Tube Fittings are engineered to provide exceptional corrosion resistance, mechanical strength, and durability for demanding marine and industrial applications. Manufactured from a copper-nickel alloy containing 70% copper and 30% nickel, these fittings offer superior resistance to seawater, brackish water, and chemical corrosion while maintaining long-term mechanical stability. Each fitting is precision-crafted to ensure leak-proof, secure connections and consistent performance. Designed for piping, heat exchangers, and industrial systems, Copper Nickel 70/30 Tube Fittings deliver reliable, long-lasting solutions in aggressive environments where corrosion resistance and robustness are critical.
Copper Nickel 70/30 Tube Fittings are composed of 70% copper and 30% nickel, with small additions of iron and manganese to enhance strength, toughness, and corrosion resistance. This alloy provides excellent performance in seawater, brackish water, and chemical environments, resisting pitting, erosion, and stress corrosion cracking. Mechanically, the fittings offer high tensile and yield strength, reliable fatigue resistance, and dimensional stability under thermal cycling and fluctuating pressures. The combination of corrosion resistance and mechanical durability makes Copper Nickel 70/30 Tube Fittings ideal for long-term service in marine, industrial, and chemical systems.
