Re: Anodizing calculations (720 Rule)
Sulfuric concentration should be 15%/wt = 22.0 av oz/gal = 12 fluid ounces/gallon = 9.3%/volume = 165.3 grams/liter. Hardcoat or Softcoat both concentrations are the same.
If you are going for a jet black you gotta go with type II anodizing.
From my notes if you want black for 2024 or 6061 you need a thickness of over 3 mils. thats doing it type III hard coat at 32F. 24-36 amps per sq ft. I don't have any experience with Hardcoat just what I've read.
