Visual inspection is invisible, but the content of some trace elements in the ingredients is slightly different.
Both 3003 and 8011 can be used as raw materials for aluminum foil lunch boxes. If the state is H24, the elongation of 3003 is lower than that of 8011 aluminum foil, but the tensile strength of 3003 is higher.
Foreign products use 3003 grade aluminum foil.
