No. It is a historical standard that has been withdrawn. It should not be used for new designs unless specified in a legacy contract.

, titled "Standard Specification for Anodic Oxide Coatings on Aluminum" , is a technical specification developed by ASTM International . It outlines the requirements for porous anodic oxide coatings produced through electrolytic processes on aluminum and aluminum alloy components.

To comply with ASTM B580-79, the anodized parts must meet several performance criteria, which are verified through standard testing procedures. 1. Coating Thickness

First, many specifically call out “ASTM B580-79 (Type G)” or similar references. Contracts, procurement documents, and engineering drawings that predate the 2025 revision still require compliance with the 1979 edition. For example, chemical processing companies list “ASTM B580-79 (Type G)” as a required specification for chromic acid anodizing performed to military standards. astm b580-79 pdf

Emma's journey was not without its challenges. She encountered skeptics who doubted the market for such high-quality, custom materials. There were times when the pursuit of perfection seemed too costly, too time-consuming. However, Emma remained undeterred, driven by her belief in the value of precision and craftsmanship.

Understanding ASTM B580-79: The Standard Specification for Anodic Oxide Coatings on Aluminum

When specifying a finish on an engineering drawing, a designer will typically call out "Anodize per ASTM B580, Type [X]". Type A (Engineering / Hard Coat) , titled "Standard Specification for Anodic Oxide Coatings

| | Modern Replacement(s) | Notes | |---|---|---| | ASTM B580-79 (Type I) | ASTM D3933 (for adhesive bonding prep) | For paint adhesion, surface preparation specs are more relevant. | | ASTM B580-79 (Type II Hard Coat) | MIL-A-8625 (Type III) or AMS 2469 | Military and aerospace standards have largely superseded ASTM B580. | | General Anodizing | ISO 7599 (for decorative) or ISO 10074 (for hard anodizing) | International standards are now more common in global supply chains. |
