Title:
 Chemical Conversion Coatings on Aluminum and Aluminum Alloys
Number:
 AMS-C-5541
Revision:
 A
Scope:
 This specification covers the requirements for two classes of chemical conversion coatings formed by the reaction of chemical conversion materials and the surface of aluminum and aluminum alloys. This specification is intended specifically to provide components of military weapon systems with maximum corrosion resistance. The coating also provides a surface having better paint adhesion than uncoated aluminum. It is not intended as a general purpose coating for commercial and decorative applications.
   
Classification:
  
Classes
The chemical conversion coatings shall be of the following classes, as specified.
   
Details Description Can Do
Class 1A For maximum protection against corrosion, for surfaces o be painted or left unpainted. Yes
Class 3 For protection against corrosion where lower electrical resistance is required. Yes
 
Status:
 Active
