Cast aluminum products is treated by mechanical polishing, the metal structure is loose, there are some casting defects. To stamping aluminum products, the surface is washed white, through sanding and mechanical polishing, the surface has natural oxide film, but the film’s thickness is only 0.01-0.15μm, it is thin and uneven, it is easy to be mechanical abrasion or wear. While aluminum circle sheet for cookware is a stamped product that is anodized to create oxide film on its surface.
