In aluminum and aluminum alloys due to the different content of various other elements, such as iron, silicon, copper, etc.In chemical and electrochemical processes, the conditions required for the treatment of these impurity elements are often inconsistent with those required for the main elements.Take the etching process of the nameplate as an example * a certain etching solution, it is impossible to be effective for all impurities elements, so that the integrity and uniformity of the etching of aluminum plate with high impurity content is poor, and even the etching process can not be carried out, therefore, such as aluminum copper read gold, aluminum silicon alloy is not suitable for the production of the etching nameplate.
Nameplate aluminum, of course, with the selected process, generally speaking, the total content of impurities should not exceed 4%.
In the electrochemical process, other impurity elements in aluminum alloy, such as the content is too high, tend to destroy the composition ratio of electrolyte and affect the formation of oxide film and its adsorption of dyes.Therefore, aluminum alloy should be used selectively to make the oxidation stain nameplate.In general, when the copper content of aluminum alloy is greater than 3.7%, the oxide film quality is poor.When the content of dissolved copper in the electrolyte exceeds 0.02g/L, obvious spots or dark stripes will appear on the oxide film layer.If the aluminum alloy with high content of copper is anodized with sulfuric acid alternating current, the oxide film is green.When the silicon content of aluminum alloy is more than 0.8%, the oxide film is dark gray, and its oxidation and dyeing effects are poor.
The forging aluminum alloy has a high content of silicon, some of the superhard aluminum alloy and the aluminum alloy with no. 5 or above have a high content of copper, so they are not suitable for making the oxidation stain nameplate.Pure aluminum and most of its aluminum alloys can be used to make the oxidation stain nameplates, among which high purity aluminum, no. 1~2 industrial pure aluminum and al-mg alloy are the ideal aluminum for the oxidation stain nameplates.
