Aircraft Grade Advanced Aluminum Solutions

We develop and manufacture aircraft aluminum sheets, plates and extrusions for critical structural aerospace applications, leveraging aluminum’s exceptional strength-to-weight ratio, corrosion resistance, and formability.

With the largest portfolio of high-performance aerospace aluminum products and services, we bring light-weighting, efficiency, cost and sustainability benefits to aircraft manufacturers.

Constellium’s broad alloy portfolio and ready-to-integrate solutions are supported by one of the world’s largest R&D centers, continuously advancing alloy development, forming, joining, and sustainable manufacturing at industrial scale.

Airware®, Constellium’s Aluminum-Lithium Solutions

Developed through over 20 years of pioneering R&D, Constellium’s Airware® pushes the boundaries of engineering and unlocks the potential of aluminum. Airware®, Constellium’s proprietary aluminum-lithium solution, delivers a breakthrough in material performance—offering significantly lower density, higher stiffness, thermal stability, corrosion resistance, and superior damage tolerance. Airware® can achieve up to 20% weight reduction when paired with optimized structural design and advanced assembly methods.

With eight specialized alloys already in use, Airware® is trusted by aircraft manufacturers in critical structural components— including fuselage skins, stringers, floor structures and seat tracks, window frames, and large internal wing and fuselage components.

Airware® is fully industrialized, with one pilot casting facility at C-TEC and two casthouses at our Issoire site.

Engineering Technologies

Our ability to support high build rates with proven industrial capabilities is instrumental in helping our partners meet their performance and ramp-up goals.

In addition, our high-performance technologies bring sustainability, performance, and cost benefits to our customers. What sets us apart is the unique combination of our metallurgical expertise and our mastery of advanced processes:

Pre-Machining and Recycling to save on material cost and optimize customer scrap recycling
Friction Stir Welding (FSW) for corrosion-resistant, rivet-free joints.
Metal bonding to enhance structural integrity and reduce corrosion risk.
Innovative forming methods like stretch forming and hydroforming enabled by custom high-performance alloys.

Circular by Design: Our Commitment to Recycling

Aluminum is inherently sustainable – it is 100% recyclable without any degradation of its mechanical properties. Constellium has built its strategy around this unique advantage, integrating circularity at every stage of the product lifecycle.

Closed-loop recycling systems: We collect and reintegrate production scrap directly into our manufacturing process, ensuring no loss in performance and minimizing waste.
End-of-life recyclability: Together with our customers and partners, we are advancing technologies to enable recycling of an end-of-life aircraft, enabling the viability of a fully circular model in aviation thanks to aluminum unique recycling properties.

Designing the Next Generation of Aircraft

As the aerospace industry navigates rising environmental demands and the push for next-generation aircraft, the need for lightweight, high-performance, and scalable solutions has never been greater.

At Constellium, we have the teams, technologies, and industrial agility to address all possible scenarios. We offer lightweight, robust aluminum solutions adaptable to engine placement changes and fuel transitions, leveraging space-sector expertise to handle extreme thermal and mechanical stresses.

We are engaged with our customers and the supply chain to define the solutions of tomorrow, such as:

“Wing of the Future” project to develop advanced technologies and materials that enhance aircraft performance through lighter weight, faster assembly, and improved recyclability.
Sustainable Aviation Fuels (SAF): Our materials support the aviation industry’s transition to SAF, helping to achieve global net-zero targets while maintaining the highest standards of performance and safety.
