Anodic Treatment of Aluminum Alloys Sulfuric Acid Process, Undyed Coating
This specification establishes the requirements for undyed anodic coatings on aluminum alloys. This process has been used typically to increase corrosion resistance and to provide surfaces that will promote adherence of paint and other organic finishes, but usage is not limited to such applications. AMS2472 should be specified for coatings colored by dyeing. This process is not suitable for parts that contain joints or recesses in which the anodizing solution may be retained.
AMS2471H results from a Five Year Review and update of this specification.
