The invention relates to a high-ductility aluminum alloy material. The high-ductility aluminum alloy material comprises, by weight percentage, 0.33%-0.37% of Si, not larger than 0.16% of Fe, not larger than 0.012% of Cu, 0.47%-0.52% of Mg, 0.015%-0.025% of Mn, not larger than 0.01% of Cr, not larger than 0.012% of Zn, 0.01%-0.015% of Ti and the balance Al. According to the high-ductility aluminum alloy material, a specific formula is selected to prepare the high-performance aluminum alloy material with the high ductility and the high strength; meanwhile, the high-ductility aluminum alloy material has the beneficial effects of being light, resistant to abrasion and good in plasticity; and in addition, the heat dissipation performance is excellent, and the high-ductility aluminum alloy material can be used for manufacturing auto spare parts, high-grade doors and windows, radiator accessories and display frame shells, and is wide in market prospect.
