Anodic Treatment of Aluminum Alloys Sulfuric Acid Process, Dyed Coatings
|Publication Date:||1 January 2020|
This specification establishes the requirements for dyed anodic coatings on aluminum alloys.
This process has been used typically to increase corrosion resistance and to produce colored surfaces on aluminum alloy parts, but usage is not limited to such applications.
AMS2470 or AMS2471 should be specified for coatings to be used as a base for paint or other organic finishes. This process is not suitable for parts which contain joints or recesses in which the anodizing solutions may be retained.
This specification covers two types of coating classified as follows:
Class 1 - Coatings for Identification
Class 2 - Coatings for Decorative Purposes
When no class is specified, Class 1 shall be supplied.
Safety - Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
