Abstract

The invention discloses a method for manufacturing an aluminum-alloy double-zero aluminum foil, and the prepared aluminum foil comprises the following compositions in percentage by weight: 0.40 to 0.60 percent of Si, 0.40 to 0.60 percent of Fe, less than or equal to 0.05 percent of Cu, less than or equal to 0.05 percent of Mn, less than or equal to 0.05 percent of Mg, less than or equal to 0.05 percent of Cr, less than or equal to 0.2 percent of Zn, less than or equal to 0.1 percent of Ti, and the balance of Al. The method disclosed by the invention has the advantages that the compounds in the aluminum foil prepared by using the method disclosed by the invention are appropriate in size and are spherical, and evenly distributed; and the aluminum foil is less in the number of pinhole and good in mechanical performance.

Description

technical field [0001] The invention relates to an aluminum alloy material, in particular to an aluminum alloy double-zero foil and a manufacturing method thereof. Background technique [0002] With the improvement of people's living standards, the application of double-zero aluminum foil is developing rapidly in the fields of food, beverages, dairy products, medicine, daily chemicals, and electronic products. The reduction of the thickness of the aluminum foil makes the size, shape and distribution of the compound in the aluminum foil have a great influence on the pinhole number of the aluminum foil. The larger the size of the compound, the easier it is to form pinholes. The compound is rod-shaped and needle-shaped, and it is also easy to form pinholes. The compounds are distributed along the grain boundaries, which can easily damage the elongation of the double-zero foil and deteriorate its mechanical properties. Therefore, in the production process of double-zero alumin...
