We talked about two factors that affect the quality of oxide film: Electric Current Density and Temperature , now, we talk about the third factor -- Time. Under the same conditions of solution concentration and other processing technology, with the extension of anodic oxidation time, the generated oxide film will also be gradually thickening (within a certain range), the aperture gap (or pore space) will increase too which is good for dyeing. Under the same process conditions, on the contrary, if the anodic oxidation time is shortened, the generated oxide film will be thin, and the aperture gap (or pore space) becomes less and has trouble dyeing dark. Most of aluminium manufacturers’ anodic oxidation time is less than 20 minutes; except for some special situation, electrochemical polishing (Click on the link to learn more about electrochemical polishing) for example, shortens the anodic time to maintain brightness after anodizing. It’s necessary to extend the anodic time when ...

In 2017, The aluminum market continues to rise. In 2017, the domestic and foreign aluminum market has been boosted by the two major policies of China's production capacity and environmental protection. As of the end of December 2017, aluminum prices in the international market rose 26.6%, while domestic aluminum prices rose 17.5%. The aluminium market was dominated by China policy in 2017. In the first half year two policies had been introduced: Work Plan for Clearning up and Rectifying Illegal Projects in the Electrolytic Aluminium Industry (No. 656), and The Beijing-Tianjin-Hebei Region Measures for Prevention and Control of Atmospheric Pollution (2+26 policy). Under the influence of the two policies, China's electrolytic aluminum production capacity and production had declined month by month since June. But after prices soared, stimulated the part of the compliance of new production and spare production capacity and production capacity, the annual output of ele...
