In the different industries of aluminum application, like the automotive, construction, furniture, sports and leisure industries, the surface attractiveness is more important than its light weight. Aluminum after Anodizing as a finish can have following features: 1) long lasting surface finish quality, 2) metal effect surface finish, 3) durable, light weight and easy machining. Electrolytic coloring is the ideal solution if you would like to combine the mechanical and corrosion advantages of the oxide layer with the metal effect of the aluminum to produce a long-lasting color appearance. The deposition of metal/metal oxide in the porous oxide layer can create various colors in the same finish
