We are Riddhi Siddhi Impex, a Mumbai-based Nickel 201 Shims manufacturer and supplier, established in 2002. Our slitting lines process low-carbon nickel shim stock to ASTM B162 / ASME SB-162 in thicknesses from 0.03 mm to 5 mm, slit to a width at a ±0.1 mm tolerance. Backed by ISO 9001, 14001, and 45001 certifications with a supply capacity of 400-500 tonnes monthly, we ship across India and worldwide with EN 10204 Type 3.1 / 3.2 mill test certificates on request.
A Nickel 201 shim is a precision-thickness spacer slit from commercially pure low-carbon nickel, a grade holding 99.0% minimum nickel. The metal is ferromagnetic, melts across the 1435-1446 °C range, and carries a density of 8.89 g/cm³. Its 0.02% carbon ceiling keeps grain boundaries stable in hot service. Assemblers fit the shims at flange joints, seal faces, and instrument mounts to close a gap exactly. Nickel 201 shims are typically used in chemical processing equipment, caustic handling systems, electronic components, and aerospace flange joints.
As a reputable nickel 201 shims supplier, we properly slit every width between 3 mm and 2000 mm on our own lines. Each custom nickel shim order ships annealed soft to ASTM B162, with BA, 2B, or Matte surfaces. Quality checks run from the source coil receipt through final packing.
We provide ASTM B162 Nickel 201 shims in annealed soft condition, with three surface finishes and three edge options, supplied in a coil.

Carbon defines this specification. UNS N02201 shims hold at least 99.0% nickel, with carbon capped at 0.02% so the metal keeps its ductility through prolonged heat. The 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 Alloy 201 shims combine a 380 MPa minimum tensile strength with 40% elongation, and the grade strengthens through cold work alone; heat treatment won't harden it. ASTM B162 sets no yield requirement below 0.51 mm, so figures for thinner gauges stay indicative.

Overseas specifiers working to EN, JIS, or BS systems can match W.Nr 2.4068 shims against their regional designation below. Every coil we slit answers to each listing.
| 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 account for most of the Nickel Alloy 201 shims we slit and distribute. Purity, caustic resistance, and stability at temperature drive the choice; strength rarely does.
Caustic soda producers set Alloy 201 shims under evaporator flanges, valve bonnets, and heat exchanger supports. Sodium hydroxide attacks most metals at high concentration. Commercially pure nickel resists it at every strength, and the restricted carbon lets the same spacer sit beside lines running past 315 °C.
Battery and lead-frame builders order Ni 201 shims for tab spacing, contact backing, and cell alignment. Pure nickel conducts heat and current well, and it carries no plating to flake into an assembly. Our 0.03 mm capability covers the finest packing pieces these products call for.
Traceability governs aerospace purchasing. Engine shops fit Nickel 201 shim packs to set turbine spacing and correct hot-section alignment, and each consignment carries an EN 10204 Type 3.1/ 3.2 certificates on request. AMS 5553 material can be arranged where the drawing demands it. Packs arrive slit to size and install without trimming.
Purity decides the order in food plants. Dairy and beverage processors place these spacers on filler heads, conveyor bearings, and frames washed with hot alkaline cleaning cycles. The surface doesn't pit under repeated CIP chemistry, and the metal adds nothing to the product stream.

Nickel 201 Shims price range in India is around ₹3,800 to ₹6,650 per kg, or roughly $40 to $70 per kg for export buyers. Rates track LME nickel, and thickness, width, finish, and quantity all move the figure. As a stockist and wholesaler, we give volume discounts on bulk 201 nickel shims, so call or WhatsApp us for today's rate.
The thickness range available for Nickel 201 shims runs from 0.03 mm to 5 mm, with any width between 3 mm and 2000 mm slit to order. Requirements below 0.03 mm move into our Nickel 201 foils range.
Yes, Nickel 201 shims can serve above 315 °C. The 0.02% carbon ceiling prevents the graphitisation that weakens Nickel 200 past this temperature, which is why hot flange and furnace positions specify the 201 grade.
The typical lead time for custom Ni 201 shims is 4 to 5 days from ready stock at our Mumbai and Taloja warehouses. Urgent slitting programs dispatched in 2 to 3 days.
You can source Nickel 201 shims in India from us at Riddhi Siddhi Impex. Ready inventory in our Mumbai warehouse for immediate dispatch. As a manufacturer, stockist, dealer, and distributor, we supply buyers across India and export overseas. Call or WhatsApp us; quotes will be provided within 24 hours.
