ASTM B580-79 is a widely recognized technical standard established by ASTM International. It specifically provides the standard specification for anodic oxide coatings on aluminum.
While the standard was originally designated in 1979, it remains a foundational reference for engineers and manufacturers who need to ensure the durability and appearance of aluminum parts. What Does ASTM B580-79 Cover?
This specification categorizes anodic coatings into seven distinct types, ranging from thin decorative films to thick, wear-resistant "hard" coatings. Each type is defined by its minimum thickness and intended application:
Type A (Hard Coat): Used for maximum wear and abrasion resistance (minimum 50 thickness). astm b580-79 pdf
Type B (Architectural Class I): High-thickness coating for exterior structures exposed to severe weathering.
Type C (Architectural Class II): Moderate thickness for interior or less-exposed architectural elements.
Type D (Automotive/Decorative): Thinner coatings used for bright finishes on trim and consumer goods.
Type E, F, & G: Various degrees of decorative and protective coatings with thinner profiles for specific industrial needs. Key Requirements
The standard outlines several critical quality benchmarks that the coating must meet:
Thickness: Measured using non-destructive methods (like eddy-current) or cross-sectional microscopy.
Sealing: Tests to ensure the porous oxide layer is properly sealed to prevent corrosion. ASTM B580-79 is a standards specification related to
Appearance: Ensures the finish is uniform and free from visible defects like burns or pits. Accessing the PDF
Since ASTM standards are copyrighted, the official PDF is typically not available for free public download. To obtain a legal copy of ASTM B580-79, you can: Purchase directly from the ASTM International website.
Access through a subscription via technical libraries or corporate "Standards Connect" portals.
Use IHS Markit or Techstreet, which are authorized third-party distributors of technical standards. The exact thickness requirements for a specific Type (A-G). The testing methods used to verify the coating quality.
Comparing it to MIL-A-8625, the military equivalent for anodizing.
Here’s a draft write-up for a webpage, document description, or knowledge base entry regarding ASTM B580-79 (PDF).
Many defense and aerospace components produced from 1980 through the mid-1990s were manufactured to this specific revision. If you are maintaining aging aircraft, military ground vehicles, or naval equipment, the original drawings may explicitly call out "ASTM B580-79." To validate a repair or replacement part, engineers must reference the exact standard used at the time of original manufacturing. If you want, I can:
Patent disputes, failure analysis, and product liability cases often require reviewing the state of the art at a specific point in time. ASTM B580-79 represents the industry baseline for anodizing in the late 1970s. Legal teams and forensic engineers search for the PDF to establish what constituted "acceptable practice" when a component was originally made.
If you only need to reference the document once, some university engineering libraries maintain physical archives of old ASTM standards. Request an interlibrary loan through your local library. You may be able to view a physical copy for free, though scanning or reproduction will be limited by copyright.
A: First, explain that the standard is withdrawn. Offer to qualify to MIL-A-8625 Type III or ISO 10074, which provide equivalent or superior performance. If they insist on the original, purchase the PDF from ASTM Compass and produce a compliance plan.
What exactly did ASTM B580-79 require? The standard covered several critical aspects of anodizing aluminum, which is an electrochemical process that converts the metal surface into a durable, corrosion-resistant anodic oxide finish.
ASTM B580-79 is a historical (withdrawn) standard published by the American Society for Testing and Materials (ASTM). It specifically defined the requirements for anodic oxide coatings applied to aluminum and aluminum alloy products. The standard covered classification, properties, and test methods for hard, thick anodic coatings typically used in engineering applications requiring wear resistance, corrosion protection, or electrical insulation.
⚠️ Note: ASTM B580-79 has been withdrawn by ASTM International and is no longer maintained as an active standard. It is provided for archival and historical reference only.
