Nimonic Coil Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies nimonic 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.
Nimonic covers age-hardened nickel-chromium superalloys developed for gas-turbine hot sections. In-house slitting, cut-to-length, levelling and edge conditioning let us ship coil already sized for your press or roll former.

Chemical Composition
The family is built on 18-21% chromium in a nickel matrix, strengthened by titanium and aluminium that precipitate gamma-prime on ageing. Nimonic 90 adds 15-21% cobalt; Nimonic 263 uses 5.6-6.1% molybdenum.
Mechanical and Physical Properties
Aged tensile strength typically falls between 900 and 1200 MPa, with creep-rupture capability sustained to 900°C and good resistance to oxidation and sulphidation.
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 |
|---|---|
| Aerospace | Turbine blades, discs, rings and combustion hardware. |
| Power generation | Industrial gas-turbine components and hot-gas-path parts. |
| Automotive | Exhaust valves for high-performance and heavy-duty engines. |
| Heat treatment | Furnace fixtures and high-temperature springs. |
| Oil and gas | Turbine hardware and high-temperature fasteners. |
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.
