SAE AMS2469H

This specification establishes the requirements for a hard anodic coating on aluminum and aluminum alloys.

This process has been used typically to increase, by formation of a dense aluminum oxide, surface hardness andresistance to abrasion and corrosion of aluminum and aluminum-alloy parts containing, in general, less than 5% copper or 8% silicon or a total of 8% of both, but usage is not limited to such applications. Alloys with higher alloy content can be coated satisfactorily with proper precautions in processing. Careful consideration should be given when using this process on highly-stressed parts because of the resultant marked lowering of fatigue performance and on parts with sharp corners and edges where chipping may result.
