need help finding problem....

It's the 2XXX alloys that I find build a heavier layer of smut in lye based solutions.

I know the 2XXX builds less film thickness compared to other alloys for a given time, so I'm not 100% positive why less time compared to 6061 gives good results. If I anodize 2011 for the same time I do 6XXX series, it tends to get speckles in the dye, and a smutty coating.

I am not following the LCD formula either for the bulk of our anodizing, not because it doesn't give good results, but because of time considerations mainly. I am doing 6XXX series at 8 amps CD for 75 minutes in 2.5:1 solution with good results, and the 2011 amps CD for 60 minutes.

I want to experiement more too, but haven't had time. So, I am sticking with what is working for me now. Fibergeek, I would like to hear the results of your findings if and when you are ready to reveal them.

Hey, nothing succeeds like success.

It won't be if you hear about it, it will be when.
