Parts must be sealed in water or chemical solutions to improve stain and corrosion resistance, except where specifically excluded (e.g., hard coatings often remain unsealed for better wear). How to Access the PDF

ASTM B580-79 was introduced to unify the testing and certification of "hard anodizing" (Type III in later standards). It was widely adopted by:

The specification focuses on coatings where aesthetics, , abrasion resistance , and electrical properties are essential. It specifically excludes nonporous barrier layer coatings used for electrical capacitors. astm b580-79 pdf

ASTM B580-79 has been withdrawn . It is no longer an active, maintained standard. Parts must be sealed in water or chemical

The standard provides seven distinct types of coatings (A-G), primarily differentiated by their . Description Key Characteristic Type A Thickest option, typically 50 µm min. unless specified. Type B Architectural Class I Designed for maximum durability and outdoor exposure. Type C Architectural Class II General purpose for external or internal use. Type D Automotive Exterior High resistance to road salts and environmental stress. Type E Interior / Decorative Focus on appearance and moderate protection. Type F Interior / Decorative Thinner decorative layer for mild environments. Type G Chromic Acid Type

For applications where the aluminum is sheltered from the weather but requires durability and aesthetics, lower classifications are utilized. It is no longer an active, maintained standard

The standard establishes the requirements for electrolytically formed porous oxide coatings on aluminum and its alloys. These coatings are primarily used to improve appearance, corrosion resistance, abrasion resistance, and electrical properties. Core Standard Overview Designation: B580-79 (Reapproved 2019).
