With the progress of the times, many things in life are brought about by the convenience of science and technology, bringing convenient and efficient life to people. Now life is full of high technology. aluminum cast manufactory


Anodic oxidation, electrochemical oxidation of metals or alloys. Aluminum and its alloys in the corresponding electrolyte and specific process conditions, due to the role of external current, in the aluminum products (anode) on the formation of a layer of oxide film process. Anodizing, if not specified, usually refers to sulfuric acid anodization.

In order to overcome the aluminum surface hardness, wear resistance and other aspects of defects, to expand the scope of application, to extend the service life, surface treatment technology has become an indispensable part of the use of aluminum, and anodizing technology is currently the most widely used and most successful of. cnc machining parts importers

An oxide film is formed on the surface of the metal or alloy as an anode by electrolysis. Metal oxide films change the surface state and performance, such as surface coloring, improve corrosion resistance, enhance wear resistance and hardness, protect the metal surface. Such as aluminum anodizing, aluminum and its alloys placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, under specific conditions and external current, the electrolysis. The anode of aluminum or its alloy oxidation, the surface of the formation of alumina thin layer, the thickness of 5 to 20 microns, hard anodic oxide film up to 60 to 200 microns. Anodized aluminum or its alloys, improve its hardness and wear resistance, up to 250 ~ 500 kg / mm2, good heat resistance, hard anodized film melting point up to 2320K, excellent insulation, Wear voltage up to 2000V, enhanced corrosion resistance, in the ω = 0.03NaCl salt spray after thousands of hours without corrosion. The oxide film has a large number of micropores, can absorb a variety of lubricants, suitable for the manufacture of engine cylinders or other wear parts; membrane microporous adsorption capacity can be colored into a variety of beautiful and beautiful 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 parts, precision instruments and radio equipment, daily necessities and architectural decoration and so on.
