Aluminum Alloy Surface Treatment

Aluminum alloy is primarily composed of aluminum, which is a highly reactive amphoteric metal. It is corroded in both acidic and alkaline environments, as well as in humid conditions.The company has achieved significant milestones in its recent operations.Environmental conditions can also cause corrosion. To prevent rapid corrosion, anodizing is typically performed. The anodized aluminum or its alloys are then used.An aluminum oxide thin layer forms on the surface, with a thickness of 5 to 20 micrometers, while the hard anodized film can reach 60 to 200 micrometers. Anodized aluminum or its alloys, after anodic oxidation, enhance their hardness and tensile strength to 250 to 500 kg/square millimeter, possess excellent heat resistance, with the melting point of the hard anodized film up to 2320K, good insulation properties, and a breakdown voltage of up to 2000V. This also improves their corrosion resistance, remaining unaffected for thousands of hours in a 0.03NaCl salt mist environment. The thin oxide layer contains a large number of micropores that can adsorb various lubricants, making it suitable for manufacturing engine cylinders and other critical components; the micropores exhibit strong adsorption capabilities.Please provide the Chinese content you would like translated into American English.Colorful in a variety of beautiful and vibrant hues.

Aluminum alloy perforated panels, to overcome the deficiencies such as surface hardness and brittleness of aluminum alloy, to expand their application scope, and to prolong their service life, surface treatment technology has become an indispensable part of aluminum alloy usage. Anodizing technology is currently the most successful application.
