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
VS
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

Fittings are pressure-tested individually to rule out leak paths

PMI Testing

Alloy composition is confirmed lot by lot through Positive Material Identification

Third-Party Inspection

TPI can be arranged on request for larger export shipments

Erosion & Corrosion Resistance Check

Resistance to high-velocity flow and chloride attack is checked against ASTM B151

Dimensional Check

Bore, thread and center-to-end dimensions are checked against drawing tolerance

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.
