Purpose:

This specification establishes the engineering requirements for producing chemical-film coatings on aluminum alloys and the properties of such coatings.

Application:

This process has been used typically for increasing the corrosion resistance of aluminum alloy parts, as a base for paint or other organic finishes, and for repair of abraded surfaces or discontinuous anodized coatings on aluminum alloy parts, but usage is not limited to such applications. AMS 2474 should be specified when parts are used in assemblies which have electrical bonding requirements.

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.
