Nickel Alloys in Aerospace

In the aerospace industry, the selection of materials is a critical factor in performance and safety standards. Nickel alloys have risen to prominence due to their exceptional properties.
Nickel and cobalt superalloys can resist temperatures of 1,000°C or more. They’re frequently found in jet engine turbines, but also in other applications, such as jewelry, weaponry, coins, petroleum refining, marine equipment, and electronics.
Some commonly used nickel alloys in the aerospace industry:

• Inconel® 718: Known for its formidable combination of high strength, corrosion resistance, and impeccable weldability, Inconel 718 is a crucial aerospace component, used in engine parts to aircraft frames.
• Inconel® 625: This alloy boasts an unyielding resistance to high-temperature corrosion, making it an indispensable choice for aerospace ducting systems and engine exhausts.
• Monel® 400: With its remarkable resistance to the corrosive forces of seawater and various acids, Monel 400 is used in many aerospace applications, including aircraft fasteners.
• Hastelloy® C-276: Highly sought after for its exceptional corrosion resistance, Hastelloy C-276 is deployed in aerospace components exposed to aggressive chemical environments.
• Invar 36®: Used when aerospace applications require low thermal expansion, such as in precision instruments and satellite components. It is also used for tooling and dies for composite forming and cryogenic components.
• Waspaloy®: Its superior high-temperature strength is harnessed in the construction of gas turbine engines and other vital aerospace components.
• Hastelloy® X: This alloy is a high performer in high-temperature, corrosive environments, making it a reliable choice for aircraft components like combustion chambers.
• MP35N®: Known for its exceptional strength, MP35N is deployed in aerospace applications that demand robust performance, including landing gear and engine fasteners.
• Rene 41: The unique combination of high-temperature strength and corrosion resistance deems it fit for turbine blades and other critical engine components.
• Nimonic® Alloys: These alloys typically consist of more than 50% nickel and 20% chromium with additives such as titanium and aluminum. They offer outstanding creep resistance (the ability to resist distortion when subjected to prolonged compressive load) and high-temperature strength, making them a preferred choice for aircraft engine components.
