Increasing the recycle content of a production stream is one of the easiest methods to reduce the cost of wrought aluminum products. This has economic and environmental benefits, but closed loop recycling systems do not reflect the conservation of the original composition, due to so called “tramp elements”. To understand the influence of certain tramp elements, a campaign of 950 AA6008 ingots were cast reflecting the entire scope of the composition window for this alloy, and the mechanical properties subsequently analyzed
