WebAug 21, 2009 · A. We have had some success using a mixture of phosphoric acid (35 mL/L), chromium trioxide (20 g/L) and water to strip Type I (chromic acid), Type II (sulfuric acid) and Type III (sulfuric acid/oxalic acid) anodize coatings from aluminum. The solution is heated to 100 °C and usually takes less than 15 minutes to strip the anodize. WebTable 1: Etch rates of materials on the AMSystems trimming tool Target removal for aluminum is typically 200A. When targeting 200A removal based on the bulk aluminum etch rate, we typically remove 160A to 180A during the first trimming.
