Although aluminum and its alloys can be coated by electroplating to yield satisfactory finishes such as nickel/chromium or tin, much more widely practiced is the anodizing of this metal. In anodizing, the natural oxide film always present on aluminum and its alloys is replaced by a synthetic oxide, which can be more corrosion resistant, can enhance the decorative appearance, and can be colored by both organic and inorganic dyes and pigments. Surface properties such as hardness, wear resistance, emissivity, and others can be altered by suitable anodizing and chemical treatments.
