Abstract. As the “green aluminium” sector continues to grow in prominence within Australia and globally, new opportunities are emerging. Low carbon aluminium can be produced using renewable energy in the smelting of primary aluminium. However, sustainability can be improved further by utilising recycled aluminium to support a circular economy, conserving natural resources and minimising waste. The quality of secondary aluminium billet is important for both extruders and customers as it can impact extrusion productivity and profile quality. This paper examines a 6060 alloy, containing 30% pre-consumer scrap, from the perspective of an extruder. Billet metallurgical characteristics, microstructure, extrudability, mechanical properties, surface finish and corrosion testing results are reported. Considerations when extruding secondary aluminium are discussed.
