Black anodized aluminum flat bar

Black anodized aluminum flat bar is to put the aluminum row in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode. Xinyi Aluminum can make colored alumina rows.
 
Black anodized aluminum flat bar, a thin layer of aluminum oxide is formed on the surface, its thickness is 5-20 microns, and the hard anodized film can reach 60-200 microns. The anodized aluminum plate has improved its hardness and wear resistance, up to 250 ~ 500 kg/mm2, good heat resistance, hard anodized film melting point up to 2320K, excellent insulation, high breakdown voltage 2000V, enhanced corrosion resistance, no corrosion after several thousand hours in ω=0.03NaCl salt spray.


 
Black anodized aluminum flat bar has a large number of micropores in the thin oxide film, which can adsorb various lubricants, suitable for the manufacture of engine cylinders or other wear-resistant parts; the film's micropores have strong adsorption capacity and can be colored into various beautiful a
