Anodized aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, Luo acid, oxalic acid, etc.) as the anode, under the specific conditions and the effect of external current, electrolysis. The anodized aluminum plate forms a thin layer of alumina on its surface, with a thickness of 5-20 μ m, and a hard oxide film of 60-200 μ M. many friends have many misunderstandings about the anodized aluminum plate.

First, as long as it is aluminum plate or aluminum coil, it can be oxidized, but according to how customers use and what products they make,

Second, aluminum plate is divided into Cast-rolled plate and hot-rolled plate, and the effect of Cast-rolled plate oxidation is not as good as the visual effect of hot-rolled plate oxidation. The surface of Cast-rolled plate oxidation will have a lot of pressure roll marks, while the surface of hot-rolled plate is very bright.

Thirdly, according to the customer's demand, you can decide whether you want to use Cast-rolled plate for oxidation or hot-rolled plate for oxidation. If you want to use Cast-rolled plate for internal tank, just for better anti-corrosion effect, you can use Cast-rolled plate for oxidation, but you need to use hot-rolled plate for anodizing, but the price of hot-rolled plate is generally higher than that of Cast-rolled plate. Shanghai Generally, anodized aluminum plates are made here. As long as they are appearance parts, 5052h32 aluminum alloy plates are mainly used.

The anodized aluminum plate is more beautiful, beautiful, more suitable for some decorative parts, and can also be better scratch resistance, longer corrosion resistance and longer service life.
