SAE AMS2471G

This specification establishes the engineering requirements for undyed anodic coatings on aluminum alloys.

This process has been used typically to increase corrosion resistance and to provide surfaces which will promote adherence of paint and other organic finishes, but usage is not limited to such applications.

AMS 2472 should be specified for coatings colored by dyeing. This process is not suitable for parts which contain joints or recesses in which the anodizing solution may be retained.
