In particular, the architectural decorative purpose-built aluminum profiles should provide a good image. This image is a kind of decorative anodized oxidation event that is produced by the anodic oxidation. Normally the thickness of the layer of aluminum oxide is formed on the transaction made is between 1-2 microns 10-25 microns, this value increases to ensure resistance against corrosion and decorative picture taken next to the material. Aluminum profile processing as simple as an anode immersed in an acidic electrolyte and the anode current passing right between the cathode is realized. The oxide layer on the surface of the electrolyte profile consists of soluble and reaction took place. Sulfuric acid anodizing technique is the most widely practiced method of direct current. Made in matt or gloss surface profile prior to plating processes determines the desired decorative image.
For application, or optionally coloring still possible. More resistant paint applied to the material. Anodizing is an application that does not harm the environment completely recycled, scrap, even when you do not lose the value of the material.
Anodized out parts of the sea in 1923 the first industrial scale has been used to protect against corrosion. Oxalic acid anodizing the first in Japan and then widely patented in Germany in 1923, had taken place, especially in architectural applications.
