At Ganpat Industrial, Copper Nickel 90/10 Forged Fittings are produced through hot forging of certified UNS C70600 / CDA 706 billet, followed by in-house finishing that includes CNC machining, thread cutting and bore reaming. Carrying 90% copper and 10% nickel, this alloy stands up to biofouling and chloride-driven corrosion far more effectively than carbon steel or bronze – a key reason Elbow, Tee, Union, Coupling, Reducer and Plug fittings in this grade have become the standard for marine and seawater piping systems. Each fitting undergoes hydrostatic testing and PMI verification prior to dispatch. Headquartered in Mumbai, Ganpat Industrial Corporation has spent more than 25 years manufacturing and exporting copper-alloy piping components, supplying both ready stock and drawing-based custom sizes to shipyards, desalination EPC contractors and offshore fabrication units across the globe.

Frequently Asked Questions
What is the difference between Cu Ni 90/10 and Cu Ni 70/30 fittings?
90/10 carries less nickel and costs less. 70/30 carries more nickel, giving it better performance in higher-velocity seawater lines.
Which grade should I choose – 90/10 or 70/30?
90/10 suits low-to-medium velocity lines such as desalination and HVAC. 70/30 is the better choice for high-velocity or highly erosive duty like offshore risers.
Do you supply both threaded and socket weld fittings?
Yes, both are available. Ganpat Industrial forges Class 150 threaded and Class 3000/6000 socket weld fittings from the same certified heat.
Is WNR 2.0872 the same as UNS C70600?
Yes, they refer to the same alloy. WNR 2.0872 is simply the European designation for 90/10 Copper Nickel under ASTM B151 / UNS C70600.
Can fittings be supplied with a Mill Test Certificate?
Yes, this is included as standard. Every dispatch comes with an EN 10204 3.1 Mill Test Certificate at no extra cost.
