Scope

1.1 Scope. This specification covers chemical conversion coatings formed by the reaction of chemical conversion materials with the surfaces of aluminum and aluminum alloys.

Notes

Claudia's Notes:
This was formerly known as MIL-C-5541 and is another of our all-time best-selling plating specs.  

The chemical conversion coatings are of the following types:
Type I – Compositions containing hexavalent chromium.
Type II – Compositions containing no hexavalent chromium.

The materials, which form protective coatings by chemical reaction with aluminum and aluminum alloys, are of the following classes:
Class 1A - For maximum protection against corrosion, painted or unpainted.
Class 3 - For protection against corrosion where low electrical resistance is required.
