      Electronic radiator aluminum profile anodized

     The process of using aluminum or aluminum alloy products as anodes, placing them in an electrolyte solution for electrification treatment, and using electrolysis to form an aluminum oxide film on the surface is called anodizing treatment of aluminum and aluminum alloys. After anodic oxidation, an oxide film of several micrometers—hundreds of micrometers can be formed on the surface of aluminum. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decoration are obviously improved and improved.

      A material protection technology in which an oxide film is formed on the surface of a metal material in an electrolyte solution by applying an anode current. Also known as surface anodizing. After the metal material or product is anodized on the surface, its corrosion resistance, hardness, wear resistance, insulation and heat resistance are greatly improved. The most anodized metal material is aluminum. The anodization of aluminum is generally carried out in an acidic electrolyte, with aluminum as the anode.

      As the film thickness increases, the resistance also increases, and thus the electrolysis current decreases. At this time, the outer oxide film in contact with the electrolyte is chemically dissolved. When the rate of oxide formation on the aluminum surface is gradually balanced with the rate of chemical dissolution, the oxide film can reach the maximum thickness under this electrolysis parameter. The outer layer of the anodized film of aluminum is porous, and it is easy to absorb dyes and colored substances, so it can be dyed and improve its decorative properties. After the oxide film is sealed with hot water, high temperature steam or nickel salt, its corrosion resistance and wear resistance can be further improved.
