Aerospace Nickel Alloys
Aerospace Nickel Alloys for High-Temperature & Corrosive Environments
Aerospace nickel alloys are essential wherever components must survive both extreme heat and aggressive corrosion. Nickel-based alloys and superalloys deliver a powerful combination of high strength, creep resistance, fatigue performance, and excellent corrosion resistance in demanding service.
In modern aerospace and defense, these alloys are used in turbine engines, exhaust systems, hot-section hardware, structural rings, fasteners, and critical components where failure is not an option.
Aerospace Nickel Product Forms We Supply
We stock and source nickel alloys in the main product forms used in aerospace and high-temperature service, so you can match the right geometry to your machining and fabrication requirements.
Nickel round bar is used for machined parts, shafts, fasteners, and turbine components where strength, toughness, and high-temperature performance are critical. Fighter Jet Metals supplies nickel round bar in diameters from approximately 0.125″ (3.175 mm) up to 14.00″, depending on grade and specification.
Nickel flat bar is ideal for structural parts, brackets, and machined components that require a rectangular profile. It is available in a variety of widths and thicknesses and can be cut to length to match your machining and fabrication needs.
Nickel plate is used for high-load structural components, hog-outs, and hardware operating at elevated temperatures. Typical nickel plate thickness ranges from about 0.1875″ up to 6.50″, with cut-to-size options available.
Nickel sheet is widely used for formed parts, hot gas ducting, combustion components, heat shields, and enclosures in high-temperature or corrosive environments. Nickel sheet thickness generally ranges from 0.002″ up to 0.150″, supplied in coils or flat sheets depending on the alloy and application.
Aerospace Nickel Grades Available
Cobalt-Based & Nickel Superalloys
For the most demanding high-temperature and high-stress environments, cobalt-based and nickel superalloys deliver exceptional strength, creep resistance, and oxidation resistance. Alloys such as MP35N, MP159, Rene 41, L605, Waspaloy, Stellite 6B, Udimet 188, and Alloy 230 are used in gas turbine engines, hot-section components, fasteners, springs, and critical hardware where failure is not an option.
These aerospace nickel alloys are engineered to deliver stable performance at extreme temperatures and high stress.
Pure Nickel Alloys
Commercially pure nickel alloys like Nickel 200 and Nickel 201 offer excellent corrosion resistance and good electrical and thermal conductivity. They are used in chemical processing equipment, electrical components, and aerospace systems that require both corrosion resistance and reliable conductivity.
These pure nickel alloys are often paired with other aerospace nickel alloys in complex systems where both conductivity and corrosion resistance are required.
Monel Nickel Alloys
Monel alloys are nickel-copper materials with outstanding corrosion resistance in marine and chemical environments, combined with good strength and toughness. Monel 400, R-405, and K-500 are commonly used for valves, pump components, fittings, fasteners, and hardware exposed to seawater and aggressive media.
Hastelloy Nickel Alloys
Hastelloy alloys provide exceptional resistance to a wide variety of corrosive environments, including chlorides, acids, and high-temperature oxidizing conditions. Grades such as Hastelloy X, N, S, and C-276 are used in combustion chambers, hot gas ducts, chemical processing equipment, and aerospace components that operate in severe service conditions.
Inconel Nickel Alloys
Inconel alloys are nickel-chromium superalloys engineered for extreme temperature and corrosion resistance. They are widely used in turbine engines, exhaust systems, structural rings, and high-temperature fasteners. Fighter Jet Metals works with Inconel grades including 600, 601, 617, 625, 702, 706, 718, 722, X-750, 783, and G-3 to support aerospace, energy, and industrial applications.
Incoloy Nickel Alloys
Incoloy alloys are designed for high-temperature strength and oxidation resistance in structural and pressure-containing applications. They are used in furnace hardware, heat-treat fixtures, petrochemical processing equipment, and aerospace systems exposed to extreme thermal conditions. Fighter Jet Metals offers a broad portfolio of Incoloy grades, including:
Other Nickel Alloys
Beyond the standard families, Fighter Jet Metals can also supply specialty nickel alloys for unique aerospace and industrial applications, including Nichrome V, Alloy 22, Kovar K, Astroloy M, and Invar 36. These materials support high-temperature electrical elements, precision electronic components, tooling, and low-expansion structures.
Together with the main grades listed above, these specialty nickel alloys help round out our aerospace nickel alloys offering for complex programs.
Certified to AMS, MIL, and OEM Specifications
Aerospace programs demand strict adherence to recognized standards and OEM material specifications. Fighter Jet Metals can supply stainless steel and other aerospace alloys to AMS, MIL, and major company specs, including Boeing, Gulfstream, Cessna, Northrop Grumman, GE Aviation, and Pratt & Whitney.
All material is delivered with full certification, lot traceability, and documentation to support the quality and compliance requirements of aerospace and defense programs.
