Abstract
A method for manufacturing an aluminum alloy sheet may include melting aluminum alloy composition containing silicon (Si), iron (Fe), copper (Cu) and manganese (Mn) in weight % on the basis of remainder of aluminum (Al) to make cast alloy having a constant initial thickness; rolling the cast alloy to allow the initial thickness to be reduced, whereby the cast alloy is elongated to aluminum alloy sheet; and performing heat treatment on the aluminum alloy sheet.
