Ganpat Industrial Corporation produces Copper Nickel 70/30 Forged Fittings at our Mumbai forge shop with nickel content held near 30% – an alloy composition purpose-built for applications where erosion, high flow velocity and prolonged chloride exposure exceed what standard 90/10 fittings can handle. Each Elbow, Tee, Union, Coupling, Reducer and Plug is manufactured from certified UNS C71500 / CDA 715 bar stock, forged in-house under controlled heat and then finished using our own CNC machining, thread-cutting and bore-reaming setups. With nickel levels roughly three times that of the 90/10 variant, this fitting range is routinely specified for offshore riser systems, FPSO topside piping, naval shipbuilding and high-capacity desalination intake lines. Before dispatch, every batch undergoes 100% hydrostatic testing and PMI verification – nothing leaves the facility unchecked. Operating out of Mumbai for more than 25 years, Ganpat Industrial Corporation manufactures and exports copper-alloy piping components worldwide, serving shipbuilders, EPC contractors and offshore fabricators with both stocked inventory and custom fittings built to drawing specifications.

Cu Ni 70/30 vs Cu Ni 90/10 Forged Fittings
This comes up on almost every seawater or offshore line list – here’s how the two grades compare side by side.
Cu Ni 70/30 Forged Fittings
- UNS C71500 • ~30% nickel content
- Superior erosion & corrosion resistance
- Rated for higher flow velocity piping
- First choice for offshore & naval lines
Cu Ni 90/10 Forged Fittings
- UNS C70600 • ~10% nickel content
- Lower cost, faster availability
- Suited for low – medium seawater velocity
- Common choice for desalination & HVAC lines

Frequently Asked Questions
Why does Cu Ni 70/30 cost more than Cu Ni 90/10?
It has about three times more nickel, which raises cost but improves erosion and seawater resistance.
Where should 70/30 be used instead of 90/10?
Use 70/30 for offshore, naval and high-velocity lines. 90/10 suits slower desalination and HVAC systems.
Do you supply both threaded and socket weld types?
Yes, Class 2000 threaded and Class 3000/6000 socket weld, both from the same 70/30 heat.
Is WNR 2.0882 the same alloy as UNS C71500?
Yes, WNR 2.0882 is just the European name for the same Copper Nickel 70/30 alloy.
Is a Mill Test Certificate included with every order?
Yes, an EN 10204 3.1 certificate comes free with every dispatch.
