I see on the 720 Rule Calculator that the Current Density is set to 6.0 amps. Yet in the Caswell instructions, 4.5 amps is specified.

With the part sizes I am going to anodize - at 6.0 current density, it comes out at 3.48 amps for 120 mins (1 mil) and at the 4.5 amp current density - it comes out to 2.61 amps for 160 mins.

I am using the 3:1 water/acid ration and a constant current PS. Material is 6061 or 7075.

Thoughts? (first time doing this BTW...)

Thanks in advance.
