Which Nimonic grades does Aurico Alloys supply?

Nine grades: Nimonic 75, 80A, 81, 86, 90, 105, 115, 263 and 901. All are held in stock or arranged with the manufacturer depending on grade and quantity.

What is the difference between Nimonic 75 and Nimonic 80A?

Nimonic 75 is a solid-solution nickel-chromium alloy, chosen for oxidation resistance and for how readily it forms and welds. Nimonic 80A adds titanium and aluminium so it can be age-hardened, which raises its strength at temperature well above 75 but makes it harder to fabricate.

Q: What forms is Nimonic available in?

Sheet, plate, round bar and foil, cut to size. Tell us the grade, the form, the size and the quantity and we will confirm availability and lead time.

Q: Do you supply Nimonic with mill test certificates?

Yes. Material is supplied against EN 10204 3.1 mill test certificates.

Aurico Alloys LLP supplies nine Nimonic® grades from Mumbai, in sheet, plate, round bar and foil. Held in stock or arranged with the manufacturer, depending on grade and quantity.

Nimonic is a family of nickel-chromium superalloys developed for service where the load is carried at temperature rather than in spite of it — gas turbine hot sections above all. The family divides cleanly in two. The solid-solution grades take their strength from the alloying elements in the matrix and stay easy to form and weld. The age-hardened grades add titanium and aluminium, which precipitate a strengthening phase during heat treatment and buy a great deal of creep strength at the cost of being harder to fabricate.

Nimonic Grades Supplied

Nimonic grades supplied
Grade	UNS	Type	Chosen for
Nimonic 75	N06075	Solid solution	Oxidation resistance with good formability and weldability
Nimonic 80A	N07080	Age hardened	The original turbine blade alloy; strength at temperature
Nimonic 81	—	Age hardened	Resistance to high-temperature corrosion
Nimonic 86	—	Solid solution	Molybdenum-bearing, for strength without age hardening
Nimonic 90	N07090	Age hardened	Cobalt added over the 80A base for higher creep strength
Nimonic 105	—	Age hardened	Higher operating temperature than 90
Nimonic 115	—	Age hardened	The highest creep strength in the family
Nimonic 263	N07263	Age hardened	Age hardened but picked for weldability, so it suits sheet fabrications
Nimonic 901	N09901	Age hardened	Iron-bearing disc alloy, for large rotating sections

A dash means Special Metals publishes no UNS number for that grade. Confirm the specification against the mill certificate for the batch supplied.

Forms Available

Nimonic is supplied in four forms, cut to size. Other mill forms can be arranged with the manufacturer — ask, and we will confirm what is possible against the quantity.

Where Nimonic Is Used

Almost everything Nimonic does comes back to holding strength where a steel or a stainless would have crept or scaled away:

Gas turbines — blades, discs, rings and casings in the hot section
Combustion systems — combustion chambers and flame tubes, usually in 263 where the part is fabricated from sheet and welded
Automotive and diesel — exhaust valves, turbocharger components
Hot working tooling — dies and tools that stay loaded while hot
Aerospace fasteners — bolts and rings that must not relax at temperature
Furnace and heat treatment — fixtures, retorts and muffles

Certification

Material is supplied against EN 10204 3.1 mill test certificates, with chemical composition and mechanical properties for the batch. Cutting to size is done in house.
