Ⅱ-A: Anodises Aluminium In Colour And Gloss

Our colour range includes 1 blue tone. We do not use pigments, but metals to obtain the blue colour. By depositing metals in the pores and then electrochemically modify the pores (interference anodising), we can obtain the colour dark blue. Blue anodising is 100 percent UV resistant and will remain sparkling for a long time.

Ⅱ-B: Basic Of Anodizing Process

Before discussing the various anodized aluminum color or how to color aluminum, we should prickle your brain on what the process is all about. Unless you have a science background or are already deep-rooted in the process, it won't be surprising that you wonder the aluminum anodizing process. Therefore, in this section, we will summarize the basic things about the process.

Aluminum anodizing is an electrochemical process in which aluminum products' surfaces are coated using a wear-resistant oxide layer. Therefore, the products exhibit properties that improve quality and aesthetics. For example, they are durable, resistant to wear and corrosion. They also have this beautiful feel which fulfills the aesthetic requirement of most users.

Anode: 2Al plus 3H2O=Al2O3 plus 6H plus plus 6e-

Cathode: 6H plus plus 6e-=3H2

Resulting anodizing reaction: 2Al plus 3H2O=Al2O3 plus 3H2
