We are Riddhi Siddhi Impex, a Mumbai-based Nickel 201 Foils manufacturer and supplier, established in 2002. We slit low-carbon commercially pure nickel foil to ASTM B162 / ASME SB-162 and AMS 5553, from 0.03 mm to 0.08 mm thick. Our ISO 9001, 14001, and 45001-certified company holds ready stock, a monthly supply capacity of 400-500 tonnes, and ships worldwide with EN 10204 Type 3.1 / 3.2 certificates available on request.
Nickel 201 foils are thin-gauge flat products of low-carbon commercially pure nickel, holding 99.0% minimum nickel with carbon capped at 0.02%. The cap keeps grain boundaries free of graphite above 315 °C, where standard-carbon nickel embrittles. The metal melts at 1435-1446 °C, resists caustic soda at every concentration, and strengthens only through cold work. It is mainly applied in electronic and battery components and food processing equipment.
Every 201 Nickel Foil order runs through our own slitting lines. Material ships annealed (soft) to ASTM B162, in any width from 3 mm to 2000 mm, with BA, 2B, or Matte surfaces. Each coil carries a mill test certificate when requested.
We provide ASTM B162 Nickel 201 Foil in annealed soft condition, with three surface finishes and four edge options.

A 0.02% carbon ceiling separates this grade from ordinary Commercially Pure Nickel Foil. Nickel Alloy 201 Foil holds 99.0% minimum nickel; full ASTM B162 limits appear below.
| Element | Composition (%) |
|---|---|
| Nickel (Ni) | 99.0 min |
| Carbon (C) | 0.02 max |
| Manganese (Mn) | 0.35 max |
| Iron (Fe) | 0.40 max |
| Silicon (Si) | 0.35 max |
| Copper (Cu) | 0.25 max |
| Sulphur (S) | 0.01 max |
Annealed Low Carbon Nickel Foil pairs a 380 MPa minimum tensile strength with 40% elongation, so deep draws form without cracking. ASTM B162 applies its yield minimum from 0.508 mm upward; figures for thinner gauges are indicative.

International buyers can match UNS N02201 Foil against their regional standard using the table below. W.Nr 2.4068 Foil and NW 2201 Foil ship from the same stock.
| Country / Standard | Designation |
|---|---|
| USA (UNS) | N02201 |
| Europe (EN) | LC-Ni 99 |
| Germany (W.Nr) | 2.4068 |
| Japan (JIS) | NW 2201 |
| UK (BS) | NA 12 |
These 4 industries use the Alloy 201 Foil we slit. Buyers pick the grade where heat, caustic media, or product purity rules out standard-carbon nickel.
Caustic soda plants wrap evaporator internals, gasket windings, and probe sheathing in Nickel 201 foil. Sodium hydroxide leaves the surface untouched at any strength, hot or cold. Because carbon is at 0.02% maximum, linings run above 315 °C without embrittling, a duty standard nickel foil cannot cover.
Battery makers weld thin Nickel 201 tabs and current collectors because the grade conducts heat and electricity well and takes resistance welds cleanly. Shielding cans and magnetostrictive sensor parts use the same stock. Foil slit to ±0.1 mm drops straight into the automated cell assembly without edge trimming.
Dairies and beverage plants line contact surfaces and seal faces with this foil. Hot alkaline cleaning cycles don't leach or stain commercially pure nickel, so product purity holds batch after batch. Fabricators also fold the material into gaskets and diaphragms for hygienic pipework.
AMS 5553 Foil serves aerospace buyers for heat shielding, instrument diaphragms, and brazed laminates near engine hot zones. The low-carbon chemistry keeps ductility through repeated thermal cycles above 315 °C. Certified UNS N02201 foil ships with full traceability for audit-heavy aerospace programmes.

The price range of 201 Nickel Foils in India is around ₹2,500-₹3,000 per kg. Overseas, it's generally $30 to $50 per kg. Foil runs above the sheet of the same grade; thin gauges take extra rolling and slitting. Rates track LME nickel, so call or WhatsApp us for a current price list and wholesale discounts.
The difference between Nickel 200 and Nickel 201 foil is the carbon content. Nickel 201 caps carbon at 0.02% against 0.15%, so it stays ductile in continuous service above 315 °C.
We supply Nickel 201 foil from 0.03 mm to 0.08 mm thick, slit to any width between 3 mm and 2000 mm at ±0.1 mm.
Nickel 201 foil is covered by ASTM B162 and ASME SB-162 for general service, and by AMS 5553 for aerospace material.
The main applications of Nickel 201 foil are caustic soda equipment, battery tabs and shielding, food processing surfaces, and aerospace heat shields.
Some of the finishes we offer are BA, 2B, and Matte, all in annealed soft condition.
The lead time for Nickel 201 foil orders is 4 to 5 days from ready stock, with urgent dispatch in 2 to 3 days.
