Using a withdrawn standard for new product development without written customer approval is a compliance risk. Always verify the current revision required by your contract or quality management system.
For decorative indoor use with minimal wear, requiring a minimum thickness.
When specifying a finish on an engineering drawing, a designer will typically call out "Anodize per ASTM B580, Type [X]". Type A (Engineering / Hard Coat)
ASTM B580-79 is a standard that specifically pertains to the "Standard Specification for Anodic Oxide Coatings on Aluminum." This specification covers the requirements for the evaluation and testing of anodic oxide coatings on aluminum and its alloys. The coatings are applied for various purposes, including architectural applications, electrical and electronic components, and industrial applications where corrosion resistance and wear resistance are crucial.

ASTM B580-79 remains a critical standard for defining the quality of anodized aluminum. By specifying the correct Type (A-G), manufacturers can ensure that their aluminum components are properly protected against corrosion and wear, while achieving the desired aesthetic results.
ASTM B580-79 defines the standard specification for anodic oxide coatings on aluminum, establishing requirements for porous coatings based on seven types ranging from heavy-duty Hard Coat (Type A) to decorative finishes (Types E-G). These specifications dictate thickness, surface preparation, sealing requirements, and corrosion resistance standards. For the official, updated specification, visit ASTM International
The primary utility of the ASTM B580 standard is its clear classification system. It divides anodic coatings into six distinct types based on their minimum thickness and intended application environment.

Thin Protective — Used where minimal dimensional change is required.
Months turned into years, and Emma's company began to flourish. Architects and designers from around the world took notice of her exceptional products, which seemed to push the boundaries of what was thought possible with aluminum. From sleek, modern skyscrapers to intricate, art-like installations, Emma's materials became the choice of creatives seeking to leave a lasting mark.
: Thinner than Class I, offering excellent durability for indoor environments like handrails, trim, and retail fixtures. Type D (Automotive / Interior Trim)
One day, Emma received an inquiry from a renowned architect, interested in her company's capability to produce a custom facade for a new landmark building. The architect's specifications were stringent, essentially demanding a product that would set a new standard for architectural excellence. When specifying a finish on an engineering drawing,
It was a chilly winter morning when Emma first stumbled upon the document that would change her perspective on craftsmanship forever: ASTM B580-79 PDF. A materials engineer by training, Emma had always been fascinated by the marriage of art and science, particularly in the realm of architectural design. Her quest for perfection led her to explore the nuances of aluminum alloy anodized architectural flat sheets, a seemingly mundane topic that, to her surprise, held a world of complexity and beauty.
Whether the part requires (crucial for Type B-F corrosion resistance).
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.
