Each of the alloys were individually anodized at 6amps per sq. ft. current density for a period of 90 minutes for a projected ano thickness of .75mil. Dying was done with black, because that color typically requires a full 1mil thickness (at least for 6061) to come out good. Each of the samples were laid out in the same order as above for side-by-side color comparison. As expected, the 2024, and the 7075 dyed deep black, and the 5086, and 6061 were a bit light.
