Nickel Alloy Coil Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies Nickel Alloy Coil from ready stock in Mumbai to customers across India and in more than 40 export markets. Coil is the most economical way to buy sheet-gauge material when parts are blanked, roll-formed or slit to strip, because it removes the cut-length premium and keeps the surface consistent along the whole run.
Nickel Alloy covers nickel-base alloys combining high-temperature strength with resistance to oxidising and reducing media. In-house slitting, cut-to-length, levelling and edge conditioning let us ship coil already sized for your press or roll former.

Chemical Composition
Compositions span commercially pure nickel (99.0% Ni min in Nickel 200) through Ni-Cu (Monel 400: 63% Ni, 31% Cu), Ni-Cr-Fe (Inconel 600: 72% Ni, 15.5% Cr) and Ni-Cr-Mo-Nb (Inconel 625: 58% Ni, 21.5% Cr, 9% Mo, 3.6% Nb) systems.
Mechanical and Physical Properties
Tensile strength runs from roughly 380 MPa for annealed Nickel 200 to 830 MPa and above for Inconel 625, with service temperatures reaching 1000°C in the solid-solution-strengthened grades.
Industry Applications
How coil and strip is used
Coil and strip are continuous cold-rolled flat product, bought to be worked rather than installed as they arrive. The common routes are stamping and deep drawing of gaskets, bellows, diaphragms and seals; forming of springs and spring washers; slitting to narrow strip for electrical contacts, battery tabs and current collectors; shim and vessel-lining stock; and as the feedstock from which welded tube and pipe are made. Thickness tolerance and temper matter more here than they do in any other form, because the material has to survive the press.
| Industry | Typical use |
|---|---|
| Chemical processing | Reactor internals, heat exchangers and transfer piping handling acids, chlorides and caustics. |
| Oil and gas | Downhole tubing, wellhead components and sour-service equipment meeting NACE MR0175. |
| Power generation | Superheater and reheater elements, boiler tubing and flue-gas desulphurisation systems. |
| Aerospace | Engine casings, exhaust systems and airframe fasteners. |
| Marine | Seawater piping, condenser tubing and offshore platform hardware. |
Testing and Certification
Every consignment ships with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. Depending on grade and specification we can supply positive material identification (PMI), ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM A262 or G28, and third-party inspection release notes from Lloyd's Register, Bureau Veritas, SGS or TUV.
Aurico Alloys LLP operates an ISO 9001:2015 quality management system. Material for sour service can be supplied certified to NACE MR0175 / ISO 15156 where the grade permits.
