We are Riddhi Siddhi Impex, a Mumbai-based Inconel 602 Foils manufacturer and supplier, established in 2002. We slit high-carbon Alloy 602 CA foil from strip conforming to ASTM B168 / ASME SB-168, 0.03 mm to 0.08 mm thick, holding widths to ±0.1 mm on narrow slit widths. Our ISO 9001, 14001, and 45001-certified facility maintains ready stock, with a monthly supply capacity of 400 to 500 tonnes, and issues EN 10204 Type 3.1 mill test certificates as standard, with Type 3.2 on request.
Inconel 602 foils are ultra-thin flat products of a nickel-chromium-iron alloy carrying 24.0 to 26.0% chromium, 1.8 to 2.4% aluminium, and a deliberately high 0.15 to 0.25% carbon. Aluminium and chromium together grow an alumina-rich scale on the surface, while small yttrium and zirconium additions keep that scale anchored during thermal cycling. This combination provides oxidation and carburisation resistance in service up to 1200 °C. Inconel 602 foils are typically used in industrial furnace components, petrochemical reformers, chemical reactors, and automotive exhaust systems.
We slit every Nickel Alloy 602 foil in-house from Inconel coil. Material is supplied in the solution annealed condition to ASTM B168, at any width from 3 mm to 2000 mm, in your choice of surface finish and edge, with a mill test certificate on every order.
We provide ASTM B168 Inconel 602 CA foils in the solution annealed condition, precision-slit to widths from 3 mm to 2000 mm, with four surface finishes and four edge options.

Aluminium distinguishes this grade from plain nickel-chromium alloys. At 1.8 to 2.4%, it forms the alumina layer that shields Alloy 602 CA foils, and yttrium keeps that layer bonded through heating cycles. The nominal composition of UNS N06025 to ASTM B168 appears below.
| Element | Composition (%) |
|---|---|
| Chromium (Cr) | 24.0 to 26.0 |
| Nickel (Ni) | Balance |
| Iron (Fe) | 8.0 to 11.0 |
| Carbon (C) | 0.15 to 0.25 |
| Aluminium (Al) | 1.8 to 2.4 |
| Titanium (Ti) | 0.10 to 0.20 |
| Yttrium (Y) | 0.05 to 0.12 |
| Zirconium (Zr) | 0.01 to 0.10 |
| Silicon (Si) | 0.50 max |
| Manganese (Mn) | 0.15 max |
| Copper (Cu) | 0.10 max |
| Phosphorus (P) | 0.020 max |
| Sulphur (S) | 0.010 max |
Solution annealed UNS N06025 foil combines a 680 MPa minimum tensile strength with 30% elongation, so it forms cleanly yet keeps strength at red heat. ASTM B168 applies the yield minimum at qualifying gauge; values for foil gauges are indicative.

Procurement teams that order W.Nr. 2.4633 foils or NiCr25FeAlY receive the same alloy we stock as UNS N06025. Cross-reference each regional designation in the table below.
| Country / Standard | Designation |
|---|---|
| USA (UNS) | N06025 |
| Europe (EN) | NiCr25FeAlY |
| Germany (W.Nr) | 2.4633 |
These three industries specify most of the Nickel Alloy 602 foils we produce. In each, buyers pick the grade for oxidation and carburisation resistance at temperatures where standard heat-resistant alloys scale away.
Furnace builders and heat treaters wrap radiant tubes, line muffles, and shield thermocouples with Inconel 602 CA foil. The alumina scale stays put through repeated heating and cooling, so thin sections work near 1200 °C, resisting spalling. Foil-gauge material also forms flexible seals around retort doors and furnace joints.
Reformer and cracker operators fit Nickel Alloy 602 foils as gasket windings, catalyst support wraps, and protective linings in carburising process streams. Metal dusting degrades conventional grades in syngas service; high chromium and aluminium content slows that attack sharply. Narrow slit widths wind tightly around irregular hardware.
Exhaust component makers press Alloy 602 CA foil into catalyst substrate supports, high-temperature gaskets, and heat shields. The grade resists shedding oxide flakes that would foul a catalyst, and it holds strength where exhaust gas runs hottest. Gauges down to 0.03 mm trim component mass without shortening service life.

The Inconel 602 foil price in India runs around ₹3,800 to ₹5,700 per kg, or roughly $44 to $66 per kg for export orders. Thin foil gauges carry a premium over strip of the same grade. Nickel exchange rates, width, finish, and quantity all affect the final price, so call or WhatsApp us for today's rate.
We slit Inconel 602 foils from 0.03 mm to 0.08 mm thick and to any width between 3 mm and 2000 mm, with width held to ±0.1 mm on narrow slit widths. Odd sizes are routine for our slitting lines.
Inconel 602 CA foils contain 24.0 to 26.0% chromium, 8.0 to 11.0% iron, 1.8 to 2.4% aluminium, and 0.15 to 0.25% carbon, plus 0.05 to 0.12% yttrium, with nickel as the balance.
Inconel 602 foils conform to ASTM B168 / ASME SB-168, the specification covering nickel-chromium-iron alloy plate, sheet, and strip. Foil ships as ultra-thin strip under the same standard.
Finishes available for Inconel 602CA foils include BA (Bright Annealed), 2B, Matte, and Matte PVC, with slit, mill, deburred, or round edges.
The lead time for Inconel 602 foils is 4 to 5 days from ready stock, and urgent IN602 foil orders can dispatch in 2 to 3 days from Mumbai or Taloja.
You can source Inconel 602 foils in India from us at Riddhi Siddhi Impex. Our Mumbai warehouse holds N06025 foil in stock for immediate dispatch. As a manufacturer, stockist, and exporter, we serve buyers across India and overseas. Phone or WhatsApp us; we provide quotations within 24 hours.
