anodized aluminium profile
Anodized aluminium extrusion profile is a compact alumina coating on the surface of aluminum and aluminum alloy in order to prevent further oxidation, and its chemical properties are the same as alumina. But unlike the ordinary oxide film, the anodized aluminium profile can be dyed by electrolytic coloring.
Anodized aluminium extrusion aluminium profile is the most widely used and most successful technology in the surface technology of aluminum, and it is also the most comprehensive and comprehensive technology for research and development. The anodic oxide film of aluminum has a series of excellent properties and can meet various needs. Therefore, it is known as a universal surface protection film for aluminum.
