Abstract

The invention relates to the technical field of environmental protection, and discloses a light environmentally-friendly aluminium alloy profile with uniformly distributed high-strength particles. Thelight environmentally-friendly aluminium alloy profile comprises the following raw materials by weight percent (wt%): 1.0 wt% 3.0 wt% of Mg, 0.6 wt% 0.9 wt% of Si, 0.4 wt% 1.0 wt% of Gu, 0.8 wt% 1.0wt% of As, 0.2 wt% 0.6 wt% of Ti, 0.4 wt% 1.0 wt% of Mn, 2.0 wt% 4.0 wt% of Fe and 0.4 wt% 0.6 wt% of Cr, and the balance being aluminium and unavoidable impurities. According to the light environmentally-friendly aluminium alloy profile, Gu and Mg are selected and utilized, Gu and Mg form ageing precipitates which facilitate strength improvement under low-temperature artificial ageing treatment of solution strengthening and coating baking treatment, age hardening capacity is exerted, and an aluminium alloy plate has bending machinability like extrusion formability and hemming machinability; during artificial ageing treatment of solution strengthening and coating baking treatment, Mg and Gu form the ageing precipitates which facilitate strength improvement, and age hardening capacity is exerted; and besides, Mg is a necessary element for achieving 300-MPa-or-above yield strength of a panel, and strength of an environmentally-friendly aluminium alloy can be improved more effectively.

Description
