Household aluminum foil material and preparation method of household aluminum foil

Abstract

The invention relates to the preparation of an aluminum alloy material, in particular to a household aluminum foil material and a preparation method of the household aluminum foil. The aluminum alloy material comprises the following alloy components by weight percent: 0.2-0.25% of Si, 0.77-0.83% of Fe, 0.05% of Cu, 0.1% of Zn, 0.05% of Ti and the balance Al. The material combines the advantages of the series 1 alloy and the 8011 alloy, has low strength, high elongation rate, high surface quality and good rolling stability; and by adopting the material, the production efficiency and yield can be effectively increased and the production cost can be reduced. The hole number of the household aluminum foil prepared by the method is below 200 per square meter, the tensile strength is 80-100Mpa and the elongation rate is no less than 1%.

Description

technical field

[0001] The invention relates to the manufacture of aluminum alloy materials, in particular to a household aluminum foil material and a manufacturing method of the household aluminum foil. Background technique

[0002] At present, the aluminum alloys used to produce household foils in the market are generally 1235 and 8011 alloys. The use of 1235 alloy to produce household foil has the advantages of good surface quality and fewer pinholes in the aluminum foil, but due to the low alloy content and soft strength, it leads to poor rolling performance, resulting in problems such as low production efficiency and yield; and the use of 8011 alloy In the production of household foil, although the strength is high and the rolling stability is good, due to the characteristics of the alloy itself, the number of pinholes often exceeds the standard, which affects the use of aluminum foil.
