Uday Flanges, situated inDubai, UAE, is one of the prominent Copper Nickel 70/30 Flanges manufacturers and suppliers, configured to perform exceptionally in corrosive and sea environments. Renowned for high-quality excellence and strict compliance with ASTM, ASME, and international standards, Uday Flanges provides service to major industries like shipbuilding, offshore oil & gas, desalination, and chemical processing. By employing state-of-the-art manufacturing methods and stringent quality checks, the company produces Copper Nickel flanges that exhibit superior seawater resistance, high mechanical strength, and extended service life in stressful applications.
Copper Nickel 70/30 Flanges are produced from the C71500 alloy consisting of around 70% copper and 30% nickel, with minor additions of iron and manganese to provide strength and corrosion resistance. This alloy offers superior corrosion, erosion, and biofouling resistance in saltwater. Its mechanical properties consist of 380–550 MPa tensile strength and excellent ductility and weldability. They come in different types such as weld neck, slip on, blind, and socket weld types and are frequently employed in high-pressure marine and industrial applications owing to their high strength and reliability.

Copper Nickel 70/30 Flanges are extensively employed in offshore platforms, shipboard piping systems, desalination plants, and marine engineering. They are suitable for seawater intake and discharge systems, ballast water systems, condenser tubes, and heat exchangers due to their resistance to marine growth and seawater corrosion. They are also utilized in chemical plants where there is a need for resistance against brine and other aggressive fluids. 70/30 alloy provides more strength and erosion resistance than 90/10, and as such, it is applicable in high-velocity fluid environments. Such flanges ensure a good, durable solution for extreme and saline working environments.
