Black Anodized Aluminum Sheet

2023-06-07

The black anodized aluminum sheet is oxidized, and a thin layer of aluminum oxide is formed on the surface, the thickness of which is 5-20 microns, and the hard anodized film can reach 60-200 microns. The black anodized aluminum plate improves its hardness and wear resistance, which can reach 250-500 kg/mm2, good heat resistance, the melting point of the hard anodized film is as high as 2320K, excellent insulation, and the breakdown voltage is as high as 2000V, enhanced corrosion resistance, no corrosion after thousands of hours in ω=0.03NaCl salt spray. There are a large number of micropores in the oxide film thin layer, which can absorb various lubricants, and is suitable for manufacturing engine cylinders or other wear-resistant parts; the film micropores have strong adsorption capacity and can be colored into various beautiful and bright colors. Non-ferrous metals or their alloys (such as aluminum, magnesium and their alloys, etc.) can be anodized.

Chemical black anodized aluminum sheet is the treatment process in which part of the base metal of the aluminum sheet reacts in a weakly alkaline or weakly acidic solution to thicken the natural oxide film on the surface or produce other passivation films. The commonly used chemical oxide film for anodized aluminum sheet is chromic acid film and phosphoric acid membranes, which are both thin and absorbent, and can be colored and sealed.

Anodized aluminum sheet can provide natural color anodized aluminum sheet, film aluminum oxide sheet, provide 1060 anodized aluminum sheet, 3003 anodized aluminum sheet, 5052 anodized aluminum sheet and other anodized aluminum plate products, the black anodized aluminum sheet of Haomei Aluminum is with high quality, we also supply natural color anodized aluminum sheet, providing all kinds of anodized aluminum sheet, anodized aluminum coil, film aluminum oxide sheet and other products.
