Zusammenfassung:	The disclosure is directed to aluminum alloys made from recycled components. The alloys have copper (Cu) from 0.051 to 0.10 wt%, chromium (Cr) from 0.01 to 0.10 wt%, zinc (Zn) from 0.02 to 0.20 wt%, manganese (Mn) from 0.03 to 0.10 wt%, iron (Fe) in an amount of at least 0.10 wt%, silicon (Si) in an amount of at least 0.35 wt%, magnesium (Mg) in amount of at least 0.45 wt%, and the remaining wt% being Al and incidental impurities. In other aspects, the disclosure is directed to aluminum alloys having copper (Cu) from 0.010 to 0.050 wt%, chromium (Cr) from 0.01 to 0.10 wt%, zinc (Zn) from 0.01 to 0.20 wt%, manganese (Mn) from 0.03 to 0.10 wt%, iron (Fe) in an amount of at least 0.10 wt%, silicon (Si) in an amount of at least 0.35 wt%, magnesium (Mg) in amount of at least 0.45 wt%, and the remaining wt% being Al and incidental impurities. The b* color of the alloys ranges from -2 to 2, and the L* color ranges from 70 to 100.
