Anodized aluminum flat bar

Anodized aluminum flat bar produced by Signi Corporation of China is to place the aluminum bar in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and perform electrolysis under specific conditions and applied current.



Anodized aluminum flat bar and a thin layer of aluminum oxide is formed on the surface. The thickness of the aluminum oxide is 5 to 20 micrometers, and the hard anodized film can reach 60 to 200 micrometers. Anodized aluminum flat bar has improved its hardness and abrasion resistance, which can reach 250 ～ 500 kg / mm2, good heat resistance, the hard anodized film has a melting point of up to 2320K, excellent insulation, and breakdown voltage resistance up to 2000V, enhanced corrosion resistance, no corrosion for thousands of hours in ω = 0.03NaCl salt spray. The thin layer of the oxide film has a large number of micropores, which can adsorb various lubricants, which is suitable for manufacturing engine cylinders or other wear-resistant parts. The film micropores have strong adsorption ability and can be colored into various beautiful colors. Non-ferrous metals or their alloys (such as aluminum, magnesium and their alloys) can be anodized
 
Signi Anodized aluminum flat bar is widely used in machinery parts, aircraft and automobile parts, precision instruments and radio equipment, building decoration, machine housing, lighting, consumer electronics, crafts, household appliances, interior decoration, signage, furniture, automotive decoration and other industries.
