In a worldwide effort to reduce energy consumption and meet emission targets, industry around the globe assesses its complete value chain. AMAG (Austria Metal AG) is able to supply low carbon footprint products by high recycling rates combined with low emission primary aluminium and alloying elements on the one hand and energy efficient production processes on the other hand.

The present work focuses on the metallurgical challenges arising from the drive for high recycled contents in 6xxx series alloys for automotive applications. In 6xxx series alloys, higher recycling rates ask for broader compositional windows. Therefore, the effects of varying iron, magnesium and copper contents on microstructure, age hardening response and mechanical properties are studied. Increasing iron contents mainly lead to an increase in primary intermetallic phases which has a negative effect on bendability. Increasing magnesium and copper contents directly increase ageing kinetics and strengthening potential while simultaneously reducing bendability. A thorough understanding of metallurgical physical processes leads the way to a more effective use of energy.
