Making Aluminium Stronger
Not all aluminium is created equal. At EGA Leichtmetall, our aluminium foundry combines the highest precision and quality with extensive experience and flexibility. In every bar. Continuous casting was invented at the Hannover plant as early as the 1920s and is still the most significant production method for aluminium billets today. We are continuously developing continuous casting with our own hot-top moulds. EGA Leichtmetall produces aluminium of the highest quality and grade.
Secondary aluminium
At EGA Leichtmetall, we have been continuously optimising our processes for the use of recycled aluminium for over 30 years and can offer application-specific alloys in our foundry that can set new standards.
Aluminium production – quality “Made in Germany”
With two 50-ton channel induction furnaces and a 10-ton mobile crucible furnace, our aluminium foundry produces more than 35,000 tons of aluminium annually in Germany. Our team of international minds stands for fairness and sustainability when it comes to cooperation based on shared values based on transparency and reliability.
Quality check after each step
To produce high-strength aluminium in premium quality, our facilities are equipped with the latest technology and a diverse range of machinery complete with our own in-house laboratory. State-of-the-art measuring equipment, a state-of-the-art laboratory process data management system (LPDM) and fully automated ultrasonic testing equipment from renowned manufacturers ensure every one of our customers‘ requirements is met and enable our foundry to maintain consistently high-quality levels for every ingot.

Overview of our main alloys
Definition of continuous casting
Continuous casting is the process of casting billets as a single piece in the form of a strand. Continuous casting is when the aluminium is poured through a bottomless mould and then withdrawn with a solidified shell and usually still liquid core in a downward, sideways or upward direction. After solidification, the strand is pulled out of the casting platform.
In our Hannover foundry, castings are cast as round billets up to a length of 7,000 mm using the level vertical continuous casting process. The dimensional range of the moulds extends from a diameter of 162 mm up to 1,150 mm, also depending on the alloy and number of strands.
