Aluminium solutions for tomorrow’s car body inner structure and outer skin from a single source
Aluminium is a key material in modern vehicle manufacturing. Speira develops tailored rolled aluminium products for inner and outer body applications, combining lightweight design, safety, design flexibility, and sustainability.
Planning a new car body project? Our experts are here to help.
Whether you’re starting with a first idea, a specific component requirement, or a planned material transition, our team supports you from alloy selection through to series integration. The more details you can share about the component, requirements, and quantities, the faster we can assess your inquiry and guide you toward the right solution.
SOUL. The core of construction.
Inner body applications are essential to vehicle body stability, safety, and functionality. Inner door panels, hood inner panels, reinforcements, and structural components form the functional backbone of the body structure. They ensure that components retain their shape, absorb forces in a controlled manner, and meet safety-critical requirements. With SOUL, Speira supplies raw material for process-stable aluminium solutions that combine high formability, defined energy absorption, and consistent properties across the entire series production.
- High formability for complex geometries
- Defined energy absorption for safety-critical components
- Increased strength for reduced wall thickness and component weight
- Reliable corrosion resistance for long-term component performance
AURA. The freedom of design.
Exterior body panels shape how a vehicle is perceived and must meet the highest standards for both material quality and processing. This is especially true for hoods, doors, fenders, and tailgates, which are highly visible exterior components. Once painted, even the smallest surface irregularities can affect the final appearance, while the parts themselves must still allow for sophisticated designs and complex geometries. With AURA, Speira supplies raw material for aluminium solutions that combine maximum formability, premium surface quality, and a uniform paint finish in series production.
- Premium surface quality for visible parts
- Optimized paintability for a uniform finish
- High formability for design-driven exterior geometries
- Series-ready solutions for established OEM production lines
Recycling-friendly alloys for the vehicle body of tomorrow
Tomorrow’s vehicles need to be lighter, safer, and more sustainable. Our recycling-friendly alloys give OEMs and suppliers a way to reduce the CO2 footprint of body components without compromising the proven material properties, joining performance, or process stability. The recycling-friendly variants integrate into existing series production without requiring fundamental adjustments and deliver the same quality as their conventional counterparts.
This approach reflects our purpose, “Building a circular world that works,” and is backed by concrete climate targets validated by the Science Based Targets initiative (SBTi). Our collaboration with KIRCHHOFF Automotive shows what this looks like in practice: together, we switched to a recycling-friendly variant for the underbody shield of an electric vehicle, significantly reducing the CO2 footprint of the material.
