MIL-A-8625: Anodic Coatings for Aluminum and Aluminum Alloys
MIL-A-8625 is the military specification titled Anodic
Coatings for Aluminum and Aluminum Alloys. This specification
covers the requirements for electrolytically formed anodic
coatings on aluminum and aluminum alloys for non-architectural
applications*. It gives the details, methods, and procedures
for these various coatings.
Whereas MIL-STD-171 only gives the general
description of available finishes and is a guide to the
selection of the correct type of finish.
