The invention discloses a novel energy-saving aluminum alloy profile and a manufacturing technique thereof. The novel energy-saving aluminum alloy profile comprises, by mass, 2.5%-2.9% of Mg, 2.2%-2.4% of Si, 0.03%-0.06% of Mn, 0.20%-0.50% of Cu, 0.05%-0.25% of Fe, 0.03%-0.08% of Ti, 0.03%-0.06% of Cr, 0.03%-0.06% of Zr, 0.22%-0.20% of P, 0.20%-0.30% of Sn and the balance Al. Through material proportioning, smelting, continuous squeezing, two-stage aging heat treatment and surface treatment, deformation of the aluminum alloy profile is small, the rejection rate is low, energy is saved, environmental friendliness is achieved, and grains in the structure are refined and high in uniformity.
