The anodized coatings are classified into different types based on their thickness and properties.
Materials and Manufacture
The aluminum alloy sheets and plates covered by ASTM B580-79 are made from wrought aluminum alloys. The alloys are melted, cast, and then rolled into sheets or plates. The anodizing process involves immersing the aluminum alloy sheets or plates in an electrolytic bath, where an electric current is passed through the alloy to form a protective oxide layer on its surface.
Requirements
The standard specifies various requirements for the anodized aluminum alloy sheets and plates, including:
Testing Methods
ASTM B580-79 specifies various testing methods to evaluate the properties of the anodized aluminum alloy sheets and plates, including:
Certification and Inspection
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.
