At Nasir Nickel Alloys in Manama, Bahrain, Copper Nickel 90/10 Fittings are manufactured to provide excellent corrosion resistance, durability, and mechanical strength in marine and industrial environments. Composed of 90% copper and 10% nickel, these fittings offer superior resistance to seawater corrosion, biofouling, and erosion while maintaining long-term structural integrity. Designed for critical piping systems, Copper Nickel 90/10 Fittings ensure leak-tight connections, dimensional stability, and reliable performance under high-pressure and high-velocity conditions. Their reliability makes them ideal for shipbuilding, offshore platforms, desalination plants, and power generation industries where seawater and harsh chemicals are involved.
Copper Nickel 90/10 Fittings are composed of 90% copper and 10% nickel, with small amounts of iron and manganese to enhance strength and corrosion resistance. This composition provides excellent tensile and yield strength, good ductility, and resistance to pitting and crevice corrosion in seawater and brackish environments. The fittings maintain dimensional stability and mechanical integrity under thermal cycling, high pressure, and fluid velocity stress. Copper Nickel 90/10 Fittings combine durability, corrosion resistance, and strength, ensuring reliable, leak-tight connections in seawater piping systems and chemically aggressive environments.
