How is red anodized aluminum formed?
Anodized aluminum tinting is a chemical change that involves the surface oxidation of aluminum and its alloys in an artificial manner.
Electrolytic coloring: anodizing, water washing, electrolytic coloring in metal salt aqueous solution, water washing, sealing. Practical electrolytic coloring process using nickel, tin and cobalt to color light bronze to black, selenium trioxide to gold, and copper to pink to brown.
Dyeing: Anodizing, washing, dipping in dye tank, washing, sealing, washing, drying. The inner layer of the dyeing tank is generally made of acid-resistant stainless steel, polyvinyl chloride, polypropylene, FRP glass fiber-reinforced plastic, and other materials. With nickel acetate or cobalt acetate sealing, general dyes will not dissolve from the sealing.
Impregnation with silver salt: anodizing, impregnation with silver salt, photosensitive, developing, fixing, sealing.

Structure of anodized film of aluminum alloy
Porous type: The central part of the anode layer has micropores perpendicular to the surface of the aluminum material, and most of the aluminum anode layer has a porous structure.
Barrier type: no microporous structure. Can withstand very high voltage, mainly used in electrolytic capacitors.
Dyeing and electrolytic coloring of aluminum alloy anodic oxide film The oxalic acid method anode layer is yellow; the sulfuric acid method anode layer is transparent. Dyeing, or electrolytic coloring, can color the anode layer.
Anodized Aluminum Application
Anodized aluminum sheets are widely used in machinery parts, aircraft and auto parts, precision instruments and radio equipment, architectural decoration, machine casings, lamps and lighting, consumer electronics, handicrafts, household appliances, interior decoration, signs, furniture, automotive decoration and other industries.
