The invention belongs to the technical field of production and manufacturing of aluminum
alloy, and relates to a seven-series aluminum
alloy profile and a manufacturing method thereof. The seven-series aluminum
alloy profile is prepared from the following components in percentage by weight, equal to or less than 0.5% of Si, equal to or less than 0.5% of Fe, 1.0-3.0% of Cu, equal to or less than 0.3% of Mn, 1.5-4.5% of Mg, equal to or less than 0.3% of Cr, 7.0-12.0% of Zn, 0.05-0.3% of Zr, 0.005-0.5% of Ti, equal to or less than 0.05% of each of other impurities, equal to or less than 0.15% oftotal impurities and the balance Al. According to the manufacturing method of the seven-series aluminum alloy profile, artificial
seasoning can be directly conducted without an off-line
solid solutionprocess, the performance of the product can also meet the requirements, the seven-series aluminum alloy profile which is excellent in strength and
ductility can be produced, and the efficiency is improved while the production cost is reduced.
