• Ams B Finishes Processes And Fluids Committee

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

This process has been used typically to increase corrosion resistance and provide surfaces which will promote adherence of paint and other organic finishes, and has been found useful for assemblies which have faying surfaces and/or which may trap electrolyte, but usage is not limited to such applications.

This process is primarily applicable to aluminum and aluminum alloy parts which have nominal copper content not greater than 5% by weight or total nominal alloy content not greater than 7.5% by weight, AMS 2471 being recommended for parts having higher alloy content. Coating may be dyed if specified, but AMS 2472 is recommended where a colored finish is required.
