appearance be established for each anodizing project. The
appearance of an anodized finish is influenced by more than depth of
color. These other factors include alloy, temper, gloss, surface
structure and the coloring process used.
The variety of aluminum materials and products incorporated into
anodizing projects require that an acceptable range be agreed upon
between the specifier-buyer and the manufacturer-anodizer on a
per-project basis.
Detailed information on the various processes, tests and quality
control systems referred to here can be obtained from the Aluminum
Association (AA), the Aluminum Anodizers Council (AAC), and
individual anodizing companies or other trade organizations.
Suggested specifications and quality control
procedures:
Finish: All exposed surfaces should receive an architectural
anodized finish in conformance with Aluminum Association Standard
SSA-46 or AAMA 611 standard. Processing should be sulfuric
acid or equivalent anodizing with electrolytic or immersion
deposited inorganic pigmentation in the coating. The resulting
anodized finish should be continuous, fully sealed and free of
powdery surfaces, smut and blemishes. |
