What is the or application for the finished part?
The gold standard for military and aerospace anodizing (Type I Chromic, Type II Sulfuric, Type III Hardcoat). astm b580-79 pdf
The standard is intended to ensure that the anodized finish meets specific performance criteria, particularly regarding: Visual quality and color uniformity. Abrasion Resistance: The ability to withstand wear. What is the or application for the finished part
If you need help with a specific related to these coatings or want to compare it to military standards (like MIL-A-8625), just let me know! Abrasion Resistance: The ability to withstand wear
Automotive trim and brightwork requiring moderate environmental protection. Type E (Interior / Moderate Wear) Minimum Thickness: 5 micrometers (0.2 mils)
Components are typically subjected to salt spray testing (such as ASTM B117) to evaluate how well the anodic layer protects the underlying aluminum from oxidation.
The standard notes that the final properties of the anodic coating are heavily dependent on the chemical composition and surface quality of the base aluminum alloy.
