Copper Nickel 90/10 Flanges Manufacturer & Supplier in India – UNS C70600

Copper Nickel 90/10 Flanges are widely used piping components known for their excellent corrosion resistance, durability, and reliable performance in demanding industrial environments. Made from an alloy containing 90% copper and 10% nickel, these flanges offer superior resistance to seawater corrosion, erosion, and biofouling, making them highly suitable for marine, offshore, and heat-exchange applications. The presence of small amounts of iron and manganese further enhances the alloy’s strength and stability in aggressive environments.

At Kalpataru Piping Solution, we supply high-quality Copper Nickel 90/10 Flanges (UNS C70600 / Werkstoff 2.0872) manufactured according to international standards such as ASTM, ASME, and ANSI. Our product range includes Weld Neck Flanges, Slip On Flanges, Blind Flanges, Threaded Flanges, Socket Weld Flanges, and Lap Joint Flanges, available in multiple sizes, pressure ratings, and specifications to meet diverse industry requirements.

Kalpataru Piping Solution is an ISO 9001:2015 certified manufacturer with over 15 years of experience supplying Copper Nickel flanges to marine, offshore, and industrial clients across 40+ countries. Our manufacturing facility is NACE-approved and we maintain ASME B16.5 compliance with full material traceability per EN 10204 3.1B certification.

Copper Nickel 90/10 flanges are valued for their excellent mechanical properties, including good thermal conductivity, high ductility, and strong resistance to impingement corrosion in flowing seawater systems. These characteristics make them ideal for applications in shipbuilding, condensers, pressure vessels, desalination plants, power generation, and petrochemical industries. In addition, the alloy offers excellent hot and cold workability, allowing the flanges to be easily fabricated, welded, and installed without compromising structural integrity.

With strict quality control, precision manufacturing, and comprehensive testing, Kalpataru Piping ensures that every Cu-Ni 90/10 flange delivered meets international quality standards and performs reliably in critical industrial applications.
