What is the hard anodized?

Hard anodic oxidation treatment. The main purpose of hard anodizing treatment of aluminum alloy is to improve various properties of aluminum and aluminum alloy, including corrosion resistance, wear resistance, weather resistance, insulation and adsorption. It is suitable for both deformation aluminum alloy and die-casting aluminum alloy parts.

Hard anodic oxidation film thickness of the general requirements of 25-150 um, most of the hard anodic oxidation film thickness of 50-80 um, film thickness is less than 25 um hard anodic oxidation film, used for other occasions of tooth and spiral parts, wear-resisting or insulation with anodic oxidation film thickness of about 50 um, in some special process conditions, the required thickness of production for more than 125 um hard anodic oxidation film, but must pay attention to the anode oxidation film is thicker, its outer microhardness can lower film layer on the surface of the roughness increases. Hard anodized bath, generally sulfuric acid solution and sulfuric acid added organic acids, such as oxalic acid, sulfamic acid, etc. In addition, hard anodic oxidation can be achieved by lowering the temperature of anodic oxidation or reducing the concentration of sulfuric acid.
