AlMgSi1 (EN AW 6082) – The high-strength aluminum alloy for demanding constructions
AlMgSi1 (EN AW 6082) – The High-Strength Aluminum Alloy for Demanding Constructions
The aluminum alloy AlMgSi1, known as EN AW 6082, is one of the most popular high-strength aluminum alloys for load-bearing structures. It combines high mechanical strength, good corrosion resistance, excellent weldability, and reliable machinability – ideal for technical constructions in mechanical engineering, vehicle manufacturing, and plant construction.
What is EN AW 6082 / AlMgSi1?
The alloy EN AW 6082 belongs to the 6000 series, which means heat-treatable aluminum-magnesium-silicon alloys. It offers significantly higher strength compared to EN AW 6060 and is particularly designed for load-bearing, safety-relevant components.
Through heat treatment (e.g., T6 or T651), the strength can be specifically increased.
