Knowledge

An anodized aluminum sheet metal refers to aluminum sheet that has gone through an anodic oxidation process in which the sheet surface is converted into a protective and decorative oxide film. The thickness of the film is 5 to 20 μm, and the hard anodized film is 60 to 200 μm thick. The anodized film does not corrode in thousands of hours in the salt fog of ω=0.03NaCl. It has a large number of micropores in the thin layer, which can adsorb various lubricants. Strong adsorption ability of the film microporous makes it possible for anodized aluminum sheet metal manufacturers to color a sheet with black, white, gold, blue, red paints. Anodized sheets have stronger hardness, wear resistance, heat resistance, insulating property and corrosion resistance, suitable to be made into engine cylinders or other wear-resistant parts.

An anodized aluminium sheet metal has the following features:

1. Good processability. An anodized aluminum sheet is highly decorative and moderate in hardness. It can be easily bent and formed for continuous high-speed stamping into products without complicated surface treatment, which greatly shortens the product production cycle and costs.

2. Excellent weather resistance. An anodized sheet with a standard thickness oxide film (3μm) of lasts for a long time indoors without discoloration, corrosion, oxidation or rust, and that with a thick oxide film (10 μm) can be used outdoors, lasting long without being discolored after exposure to the sunshine.

Anodized aluminum sheet metal products are widely used in machinery parts, aircraft parts, precision instruments and radio equipment, architectural decoration, machine casings, lighting, consumer electronics, handicrafts, household appliances, interior decoration, signage, furniture, automotive decoration and other industries.
