• North American Aviation constructed the skin of the North American X-15 Rocket-powered aircraft out of an Inconel alloy known as "Inconel X".[19]
• Rocketdyne used Inconel X-750 for the thrust chamber of the F-1 rocket engine used in the first stage of the Saturn V booster.[20]
• SpaceX uses inconel in the engine manifold of their Merlin rocket engine which powers the Falcon 9 launch vehicle.[21]
• In a first for 3D printing, the SpaceX SuperDraco engine that provides launch escape system and propulsive-landing thrust for the Dragon V2 crew-carrying space capsule is fully printed, the first fully printed rocket engine. In particular, the engine combustion chamber is printed of Inconel using a process of direct metal laser sintering, and operates at a chamber pressure of 6,900 kilopascals (1,000 psi) at a very high temperature.
Rolled Inconel was frequently used as the recording medium by engraving in black box recorders on aircraft.[22]
Alternatives to the use of Inconel in chemical applications such as scrubbers, columns, reactors, and pipes are Hastelloy, perfluoroalkoxy (PFA) lined carbon steel or fiber reinforced plastic.
The exhaust valves on NHRA Top Fuel and Funny Car drag racing engines are made of Inconel.
