Automotive Body Sheet – Advancing Sustainability and Performance

Comprehensive Solutions for Inner, Outer, and Structural Applications
Constellium delivers a full portfolio of Auto Body Sheet solutions engineered for inners, outers, and structural components. As the automotive industry evolves to meet stricter sustainability goals and advanced design requirements, we provide materials that strike the right balance between performance, efficiency, and affordability.
With proven expertise in aluminum alloy development, formability, and surface quality, we support our customers with technical excellence and end-to-end service, helping drive innovation across the vehicle body structure.
Inner Applications: Designed for Efficiency and Safety
Our range of solutions meet all leading OEMs’ specifications. They enable complex shapes while reducing stamped parts, delivering cost and productivity benefits through streamlined tooling, inventory, and assembly. Our solutions for hood inners balance stiffness and strength, enhancing pedestrian safety and meeting regulatory standards.
Outer Applications: Precision Surfaces with Superior Performance
Our solutions are designed to meet the specifications of leading OEMs, offering both high strength and excellent formability. With best-in-class corrosion resistance and optimized processes, our aluminum minimizes optical imperfections during forming, and enhances in-service performance.
Structural Applications: Lightweight Strength, Demonstrated Crash Performance
Our structural alloys are lighter than steel and offer higher crash performance. This advantage results from the behavior of alloys during a crash, the resistance of joints (bonded, riveted, welded), and material durability. Our expertise in joining technologies and bond durability is central to creating products that meet even the most demanding needs.
All our solutions are developed and rigorously tested to withstand structural forms of corrosion. They are excellent for under-ride protection and top-cover applications within battery enclosures.
Best-in-Class Technical Expertise
We provide a range of specialized services, including prototyping sheets, material characterization, numerical simulation, feasibility studies, product innovation, R&D analysis, problem-solving, and on-site support.
