ABSTRACT:
An improved process is provided for the production of aluminum reflective material having a higher total reflectance value. The process comprises controlling the anodizing conditions of a bright rolled aluminum alloy by immersing the alloy in a DC anodizing bath containing at least 26 wt. % sulfuric acid and the anodizing sheet at a current density of at least 1.94 amperes per square decimeter (18 amperes per square foot) at a temperature of from 15.56.degree. to 27.78.degree. C. (60.degree. to 82.degree. F.) for a time period of from about 0.5 to 10 minutes to provide a coating thickness of from about 0.06 to 0.22 mils. The process permits a highly reflective surface to be formed without subjecting the aluminum to a preliminary brightening process prior to anodizing.
