Abstract

The invention provides an AlMgSi alloy sheet and a preparation method thereof. The sheet comprises the following components by mass percent: 0.4-0.8% of Mg, 1-1.5% of Si, 0.7-0.8% of Cu, 0.3-0.4% of Mn, 0.4-0.6% of Fe, 0.1-0.2% of Zr and the balance Al. The process for preparing the sheet comprises the following steps: smelting, blank preparing, hot rolling, cold rolling, annealing heat treatment,solid solution heat treatment and aging heat treatment. The invention has the following advantages: the elements for preparing the alloy have few types, most of which are conventional metal elements,therefore, the alloy is low in cost; the alloy smelting process is simple, and the reasonable rolling process and heat treatment process ensure the ultimate tensile strength of the alloy to reach over 390Mpa; cold rolling is adopted in later stage of rolling, thereby dispensing with heating in the hot rolling process and lowering the energy consumption.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy materials, and in particular relates to an AlMgSi alloy plate and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's awareness of environmental protection, new requirements for energy saving and environmental protection have been put forward for automobiles. Among the many ways to meet this requirement, reducing the weight of the car has always been the way to pay more attention. And increasing the application of aluminum alloy in the automotive industry can just promote the solution of this problem. Therefore, aluminum alloy is favored by people as a lightweight material for automobiles and has broad development prospects. [0003] AlMgSi alloys that can be strengthened by heat treatment are more suitable for automobile body panels. In Europe and North America, many automobile manufacturers have begun to use 6××× allo...
