Coated parts must withstand specific exposure times to salt spray testing (commonly ASTM B117) without showing signs of pitting or degradation. Higher coating types (Type A and B) require significantly higher salt-spray resistance hours than thinner decorative coats. 4. Appearance and Workmanship astm b580-79 pdf

For any new product development or current quality assurance processes, purchasing the PDF is highly recommended. This ensures your operations are aligned with the latest technological requirements for anodized aluminum. The current standard is available through the ASTM International website and all major standards distributors.

The standard categorizes coatings into seven distinct types based on their intended use and minimum thickness: Industry Description Min. Thickness (µm) Engineering Hard Coat Type B Architectural Class I Type C Architectural Class II Type D Automotive—Exterior Type E Interior—Moderate Abrasion Type F Interior—Limited Abrasion Type G Chromic Acid 🛠️ Key Applications Do you need to compare ASTM B580 to

The ASTM B580 standard categorizes anodic coatings into based on their thickness, processing method, and intended environmental application. Coating Type Common Description Minimum Thickness Typical Application Type A 2.0 mils (50 µm) Extreme wear resistance, industrial gears, pistons Type B Architectural (Exterior) 0.7 mils (18 µm) Exterior building panels, window frames Type C Architectural (Interior) 0.4 mils (10 µm) Interior storefronts, trim, handrails Type D Decorative (Medium) 0.2 mils (5.0 µm) Consumer electronics, automotive trim Type E Decorative (Light) 0.1 mils (2.5 µm) Bright trim, indoor lighting reflectors Type F Flash Anodizing Less than 0.1 mils Pre-treatment for paint or temporary protection Type G Chromic Acid Anodizing 0.05 to 0.3 mils Aerospace components, fatigue-sensitive parts Key Technical Requirements of the Standard

is a critical international standard for the Anodizing of Aluminum , specifically covering requirements for electrolytically formed porous oxide coatings . Published by ASTM International , this specification ensures that aluminum parts achieve necessary levels of corrosion resistance, abrasion resistance, and aesthetic quality. Understanding ASTM B580-79

Base aluminum must undergo mechanical finishing and chemical pre-treatments before electrolysis.
