A. Class 3 is lighter in color BUT more importantly, less electrically resistant (i.e. MORE CONDUCTIVE). Heavier chromates (i.e. darker), Class 1A, are more resistant to both corrosion and electrical passage. Milt Stevenson, Jr. Syracuse, New York publicly reply to Milt Stevenson, Jr....
Aluminum alloy 2024-T3 test specimens may be used in lieu of 6061-T6 test specimens for testing class 3 coatings (see 6.10). When castings are being processed and the cleaning procedures used are detrimental to the wrought test specimens, the test specimens shall be cleaned in a proper ...
