"ANODIZING MIL SPEC QUESTION"



2000

WE ARE FAMILIAR WITH HAVING OUR PARTS MADE FROM 7075-T6 AND 6061-T6 ANODIZED, CLEAR HARD, MIL-A-8625F, TYPE III, CLASS 1 AND BLACK, Mil-A-8625 [link is to free spec spec at Defense Logistics Agency, dla.mil]F, TYPE II, CLASS 2. A CUSTOMER HAS SUPPLIED A PART DRAWING, MAT'L 6061-T6, WITH A FINISH OF CLEAR HARD ANODIZE PER MIL-Y-8625F, TYPE III, CLASS 1. I HAVE NOT FOUND INFORMATION ABOUT THE "Y" IN THE MIL SPEC! CAN SOMEONE HELP..

I believe it is a misprint. MIL-A-8625F is the most recent and widely used military specification for anodizing. This spec also states that Type III hardcoat must be 2 mils +-20%unless otherwise specified (ref. para. 3.7.2.1). I have yet to see a 2 mil hardcoat that meets the required minimum abrasive wear test requirement (para. 3.7.2.2) that can reasonably be called "clear". The normal color of a 2 mil hardcoat on 6061-T6 is usually quite dark.
