At Constellium, we’ve made it our mission to test the boundaries of aluminium for space travel. If you’re planning on crossing the stratosphere, you’ll rely on Constellium at every stage, from launch to space. Right now we’re lifting our eyes to the moon to Mars and on to the stars. It’s time to leave impossible on Earth.  


Space makes tough demands of engineering. Gravity, vibrations and temperature extremes are a constant. For materials, lightness, strength and resistance to damage and fatigue are critical to success.

Constellium has developed Airware® with space in mind. With lower density, higher stiffness, and better damage tolerance, it has proven to be safer and more reliable on every mission.

Aluminium precision casting allow for the creation of key space components. On the Ariane 5 launcher, Constellium’s precisely cast aluminium alloy impeller is an essential part of the third cryogenic main stage engine hydrogen turbo-pump.

For crew vehicles, our Airware® 2195 provides a strong, low-density material for spars, diagonal structures, and components. Our Airware® 2050 offers a combination of unique properties for structural sections, including frames, ribs, and window supports.


Over the past 10 years, Airware® 2050 joined Airware® 2195 as a preferred plate material for pressurized and non-pressurized structural components of space launchers and crew modules. Both alloys were selected by major space programs and several other global space launch organizations are performing studies and building prototype launchers with Airware® 2195 and Airware® 2050.

Constellium Airware® is used for the NASA Orion Crew Module and the new Boeing Space Launch System (SLS). And more recently, Blue Origin is also relying on Airware® for its massive orbital rocket, New Glenn.
