françaisAnodized aluminum refers to the plating of a layer of dense aluminum oxide on the surface of aluminum and aluminum alloys, which can prevent material oxidation, improve the corrosion resistance of aluminum alloys, increase the surface hardness and wear resistance of aluminum alloys, and can be dyed by electrolytic coloring. Rich in product appearance and color, so it is often used as the preferred material for 3C product shells such as mobile phones, tablet computers, and notebooks.
Today's products usually have the brand logo on the appearance and shell. On the one hand, it displays the product image, and on the other hand, it can also play a role in anti-counterfeiting. The marking of anodized aluminum shells of traditional products is to remove the anodic oxide layer and leak the silver-white effect of the aluminum substrate, or to print a black effect on the surface of the anode layer to form a brand identity; while the mirror surface (polished) of anodized aluminum is a new application in the field of marking , The difficulty is high, and the effect is high-end. It is mainly used in the logo marking of the shell of 3C products such as notebook computers, instead of the traditional sticking mirror stainless steel sheet technology.
