General Information
Aluminum Alloy Anodic Finishes
Anodizing
Anodizing is an electrochemical process in which the oxide film on aluminum is thickened by passing an electric current
through certain acid electrolytes with aluminum as the anode. Using this process, the natural oxide film (about 0.2 millionth
inch thick) can be thickened up to about 0.005 inch.
The purpose of anodizing is generally to impart to the metal surface specific properties of the oxide- hardness, corrosion
resistance, wear resistance and electrical insulation. Also, because anodic films are porous prior to sealing, anodizing
provides a means of coloring the metal with dyes. Hardness, wear resistance and color make surfaces extremely attractive
for many applications.
Color Anodizing
There are now three methods of color anodizing in common use. Sulfuric acid anodizing and dyeing: integral-color
anodizing; and sulfuric acid anodizing and electrolytically deposited color commonly called "two-step" process.
Continuous
Coil Anodizing
As a result of efforts to cut the cost of producing anodized sheet, and to offer a product with more consistent film and color
values, the "continuous coil anodizing" process was developed in the 1930's.
Coil anodizing, the process by which aluminum is fed through electronically and mechanically-controlled equipment in a
continuous sheet much the same as paper is fed through a newspaper press, offers nearly all of the advantages of batch
anodizing plus greatly reduced processing cost.
Since the system is automatic, hand labor is virtually eliminated, as are the expensive racks necessary in the batch
treatment. With the control systems now in use, human error is reduced to the minimum, and consistent quality of the
anodic film is dependent primarily on quality of the metal itself. Since color is dependent upon the uniform thickness and
porosity of the anodic film and coloring operation, the continuous coil approach offers greater color uniformity and
consistency than the hand-operated batch method.
EverBrite
Lighting Sheet
EverBrite Lighting Sheet was developed by Alcoa specifically for use in retrofitting fluorescent lighting fixtures. This coil
anodized product has a minimum total reflectivity of 86 percent with superior image clarity required by the retrofit market.

Limitations
Color Anodizing
When colored finishes are specified, exact appearance match should not be expected. Alloy composition tolerances and the
many processing variables can affect final color. While color variation may be no greater than that in other building construction
materials, greater satisfaction results when large expanses of color are avoided and colored panels are separated by
introduction of another color or by architectural breaks or changes of pane.
Alloys
Anodizing quality 5005 alloy sheet and 6063 alloy extrusions provide a generally satisfactory match. 3003 alloy sheet assumes
a yellowish cast when anodized, the condition being more noticeable with longer anodizing times. 6061 alloy extrusions in the
"as extruded" or mill finish condition are usually, somewhat dingy in appearance. If appearance is important, buffing or other
surface finishing should be specified. Anodizing produces an inherent cloudy appearance.
Sheet Thickness
Aluminum sheet in heavier thicknesses has a general tendency toward development of structural streaking, which may be
visually objectionable in architectural applications. Anodizing quality 5005 sheet is substantially free of this tendency and should
be specified when best possible finished appearance is desired.
