How Much Is The Anodic Oxidation Thickness Of Aluminum Alloy

The anodized thickness of aluminum alloy forms a thin layer of alumina on the surface, the thickness of which is 5 ~ 30 microns, and the hard anodized film can reach 25 ~ 150 microns.

Anodized aluminum or its alloy, improve its hardness and wear resistance, up to 250 ~ 500 kg/square mm, good heat resistance, hard anodized film melting point up to 2320K, excellent insulation, breakdown resistance voltage up to 2000V, enhance the corrosion resistance. In ω=0.03NaCl salt spray after thousands of hours without corrosion.

The thin layer of oxide film has a large number of micro holes, can absorb various lubricants, suitable for the manufacture of engine cylinder or other wear-resistant parts; The membrane has strong adsorption capacity and can be colored into a variety of beautiful and gorgeous colors.

Non-ferrous metals or their alloys (such as aluminum, magnesium and their alloys, etc.) can be anodized. This method is widely used in mechanical parts, aircraft and automobile parts, precision instruments and radio equipment, daily necessities and architectural decoration.
