Aluminium is used in manufacturing a range of automotive components, from chassis structures to suspension parts, for its high strength-to-weight ratio, corrosion resistance, and machinability.

Consistency across production batches ensures predictable performance and reliable assembly in high-volume production.

With the rapid growth of electric vehicles, aluminium has also become increasingly important for battery housings and electric motor components. Its lightweight properties help maximise driving range and energy efficiency, while excellent thermal conductivity supports effective cooling and safety in high-voltage systems. As the demand for electric mobility increases, aluminium alloys continue to play a key role in meeting the technical requirements of sustainable automotive solutions.

Our products are manufactured in accordance with our EN 9100:2018 certified quality management system. Ideal alloy families for automotive applications include:

Continuous casting for uniform microstructures in automotive products

At EGA Leichtmetall, we produce high-strength aluminium billets through continuous casting, ensuring uniform microstructure, superior mechanical properties, and reduced defect rates compared to conventional ingot casting. Our billets are manufactured using 100 per cent renewable electricity* and contain around 80 per cent secondary aluminium on average, supporting sustainability objectives without compromising performance.

We can produce billets up to 1,080 mm in diameter, enabling the machining of large and complex components such as wheels, engine components or extruded profiles. Our rigorous quality assurance includes multi-stage sampling and metallographic analysis. Every batch undergoes chemical composition analysis and hydrogen measurement to ensure compliance with sector-specific standards.

We collaborate with automotive manufacturers to tailor alloys and processes that achieve the right balance between strength, machinability, and cost efficiency.
