ASTM B580 is part of a family of finishing standards. Several other specifications are commonly used alongside B580 or are confused with it:
Interior trim, retail fixtures, and automotive trim. Minimum Thickness: 7.5 µm (0.3 mil)
For current anodizing specifications, refer to these active standards:
The of the aluminum substrate (as different alloys anodize at different rates). astm b580-79 pdf
Designed for harsh, heavy-duty exterior environments, this type provides enhanced coating thickness to withstand extreme weather and heavy handling. 5. Type E: Industrial Class
: To provide uniform emissivity and high dielectric strength. Document Status and Access
Specifies acceptable methods to measure coating depth, including eddy-current instruments (ASTM B244) or microscopic cross-sectioning (ASTM B487). ASTM B580 is part of a family of finishing standards
The primary purpose of this standard is to ensure that the anodized finish provides specific performance characteristics, including: Resistance to harsh environments.
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.
Used in environments that are more exposed, offering better protection against atmospheric corrosion and slight abrasive forces. 3. Type C: Architectural Class (Moderate Exterior) Document Status and Access Specifies acceptable methods to
ASTM B580-79 is important because it provides a standardized set of requirements for palladium-silver-copper alloy wire used in electrical contacts. This ensures that the wire meets certain performance and reliability standards, which is critical in electrical contact applications.
