At Nasir Nickel Alloys in Manama, Bahrain, Copper Nickel 70/30 Tubing is engineered to provide outstanding corrosion resistance, strength, and durability in marine and industrial applications. Composed of 70% copper and 30% nickel, this tubing offers exceptional resistance to seawater corrosion, biofouling, and erosion while maintaining long-term mechanical integrity. Designed for critical fluid transport systems, Copper Nickel 70/30 Tubing ensures leak-tight performance, dimensional stability, and reliability under high-pressure, high-velocity, and thermally variable conditions. Its robustness makes it ideal for shipbuilding, offshore platforms, desalination plants, and power generation industries exposed to seawater and chemically aggressive fluids.
Copper Nickel 70/30 Tubing is composed of 70% copper and 30% nickel, with small additions of iron and manganese to enhance strength, ductility, and corrosion resistance. This alloy provides excellent tensile and yield strength, high toughness, and superior resistance to pitting, crevice corrosion, and erosion in seawater and brackish environments. The tubing maintains dimensional stability under thermal cycling, high pressure, and fluid velocity stress. Copper Nickel 70/30 Tubing combines strength, durability, and corrosion resistance, ensuring reliable, leak-tight performance for critical marine, industrial, and chemical piping systems.
