Aluminium Angles extruded profile  

  Surface treatment can further improve the surface properties of aluminum. The aluminum anodizing process is quite mature, easy to operate, and has been widely used. The anodized oxide film of aluminum has high hardness, wear resistance, corrosion resistance, and can be colored, which can significantly change and improve the appearance and performance of aluminum alloys. Through pre-treatment, the surface of aluminum alloy can also be treated by powder coating and other processes, giving the aluminum surface with a metal coating, further improving the decorative performance and protective effect of aluminum.    The anodic oxide film of aluminum itself has high transparency, and the higher the purity of aluminum, the higher the transparency. The thickness, alloy composition, and treatment process of aluminum alloy materials all affect the transparency of aluminum anodizing film. If our standard aluminum extrusion shapes are not suitabl…
