FIELD: metallurgy.
SUBSTANCE: invention relates to the method for manufacturing of a strip, made of alloy of Al-Mg-Si, in which a bar for rolling is cast from alloy Al-Mg-Si, exposed to homogenisation, the bar for rolling heated to temperature of hot rolling, is exposed to hot rolling and then, if required, cold rolling to its final thickness, at the same time the hot strip has temperature of not more than 130°C directly at the outlet from the last stage of hot rolling, preferably the temperature of not higher than 100°C, afterwards the strip is wound at this or lower temperature.
EFFECT: method makes it possible to perform aluminium strips from alloy Al-Mg-Si, which have higher relative extension and accordingly higher extents of deformation when structural metal sheets are made.
