Anodic oxidation of <strong>
aluminum plate sheet</strong> produces a hard protective layer on the surface of aluminum parts, which can be used to produce Kitchenware and other daily necessities. But the anodized effect of casting aluminum is not good, the surface is not Michael Wong, but also only black. Professional anodized
aluminum sheet is a little better than it.<br>
In the selection of professional <strong>anodized
aluminium sheet</strong> technology (sulfuric acid oxidation, oxidation of oxalic acid and chromic acid oxidation) prior to aluminum or
aluminum alloy material to understand, because the material quality, the ingredients contained different, will directly affect the quality of the anodic oxidation of
aluminum products.<br>
For example, such as aluminum surface air bubbles, scratches, peeling, rough defects, after anodic oxidation, all defects will still be revealed. And the alloy composition on the surface of anodized appearance, also have a direct impact. For example, the <strong>
aluminum alloy sheets </strong>containing 1~2% manganese is oxidized to brownish blue. With the increase of manganese content in the
aluminum alloy, the surface color changes from brown to dark brown. Aluminum Alloy silicon containing 0.6~1.5%, oxidized silicon containing 3~6% were grey, grey white. Zinc containing milky color, chromium yellow to gray uneven tone, nickel containing pale yellow. In general, only the aluminum containing magnesium and titanium content greater than 5% of gold, after oxidation can be colorless, transparent and bright, smooth appearance.<br></p>
