Most anodized parts must be sealed in water or aqueous chemical solutions to improve corrosion and stain resistance, except when specifically excluded (like some Type A hard coats).
One of the most common points of confusion surrounding this standard relates to its title, "ASTM B580-79." The number "79" refers to the year the standard was originally adopted. Since then, the standard has been through several cycles of re-approval to keep it current. Key re-approval years include . Each re-approval (e.g., ASTM B580-79(2019)) confirms that the standard's technical content remains valid without major changes.
The scope of the standard defines its purpose: to ensure that these anodic coatings possess key properties for high-quality applications, such as a good appearance, high abrasion resistance, specific electrical properties, and effective protection against corrosion. astm b580-79 pdf
This comprehensive guide breaks down the purpose, classifications, technical requirements, and current status of the ASTM B580-79 specification. What is ASTM B580-79?
Thin Protective — Used where minimal dimensional change is required.

The standard requires that the anodized aluminum alloy sheets and plates be certified by the manufacturer or supplier. The certification must include a statement that the products conform to the requirements of ASTM B580-79. The products must also be inspected by the purchaser or a third-party inspector to ensure compliance with the standard.
ASTM B580 imposes several fundamental requirements that go beyond simple thickness measurements. are explicitly addressed: if the aluminum substrate has scratches, porosity, inclusions, roll or die marks, cold shuts, or cracks, any resulting defects in the anodic coating are not a cause for rejection. To minimize these issues, the specification covering the basis material or the item to be anodized should contain appropriate limitations on such basis metal conditions.
Ensuring durability for appliances like refrigerators and high-performance cookware. Since then, the standard has been through several
The number "79" indicates the year the standard was originally approved or significantly revised (1979). While newer surface-finishing standards exist, ASTM B580-79 remains a staple baseline in military, aerospace, automotive, and industrial procurement documents due to its clear, legacy classification system. Understanding the 6 Coating Types
The standard outlines specific requirements for anodic oxide coatings, including:
