Aluminium is used in the manufacturing of military vehicles, naval components, aerospace systems, and specialised systems in the defence industry.

These critical applications require precision, durability and consistency across production batches to ensure reliability and performance. EGA Leichtmetall combines decades of expertise with the flexibility to deliver high-quality, large-diameter, precisely engineered aluminium billets for demanding applications and customised to each customer’s needs.

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

Continuous casting for uniform microstructures in defence 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, complex components such as structural frames, mounting systems and large rings for advanced defence applications. Our rigorous quality assurance includes multi-stage sampling and metallographic analysis. Every batch undergoes chemical composition analysis and hydrogen measurement ensuring that every billet meets sector-specific standards.

We tailor our alloy selection and process parameters to balance strength, machinability, and corrosion resistance according to the intended application.
