Body Structure Components
Up to 40% lighter than steel, aluminium solutions are used throughout the vehicle’s structure to lower weight while providing the strength, stiffness, crash- and corrosion-resistance for a safe, comfortable ride. A lighter vehicle offers improved fuel efficiency, lower emissions and greater range for electric vehicles, helping automakers achieve their sustainability goals.

Thanks to its superior forming capabilities, aluminium components can be created in complex shapes, helping to reduce part count and assembly time. And aluminium components are well suited to multiple joining techniques, such as welding, adhesive bonding, self-piercing riveting, and others. At the end of the vehicle’s life, aluminium components can be recycled in a closed loop.
Constellium HSA6®, a Family of High-Strength 6xxx Alloys
Offering superior formability, corrosion resistance, energy absorption, and recyclability, Constellium’s HSA6® alloys are designed for aluminum extrusion-based structural components, as well as Crash Management Systems and EV battery enclosures. They allow designers to optimize extrusion shapes and reduce wall thicknesses to fit tighter package spaces and achieve a weight savings of 15-30 percent when compared to conventional aluminum alloys. In other scenarios, Constellium HSA6® is able to provide 15-30 percent additional strength to reduce intrusion in the event of a crash, protecting vehicle occupants while preserving the integrity of the vehicle and reducing potential repair costs.
