The processing methods of aluminum materials include extrusion, rolling, drawing, forging and casting, etc. The corresponding extrusion materials include profiles, tubes and bars, rolled plates, strips and foils, and drawn wires. And wire, forging and casting have forgings and castings respectively.
Extruded materials account for the vast majority of aluminum surfaces, especially extruded aluminum profiles for construction are subject to surface treatment such as anodizing or powder coating, and almost no surface treatment is required for stretched wires or wires.
