Abstract

The invention discloses a high-strength and low-thickness rare earth aluminum alloy band and a manufacturing method thereof. The rare earth aluminum alloy band comprises, by mass percent, 0.05%-0.3% of Re, 0.1%-0.2% of Mn, not larger than 0.25% of Mg, not larger than 0.50% of Fe, not larger than 0.40% of Si and the balance Al and inevitable impurities. Mn, Mg, Fe, Si and Al are selected as main components of the aluminum alloy band, the substance Re is added, meanwhile, the contents of the components are adjusted, and the finished aluminum alloy band is obtained after smelting, casting, heat treatment, hot rolling, cold rolling, annealing and slitting; and compared with an existing aluminum alloy band, the structural strength is higher, and the structural strength the same as that of the existing aluminum alloy band can be achieved by reducing the thickness by 20%.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a high-strength and low-thickness rare earth aluminum alloy strip and a manufacturing method thereof. Background technique [0002] Aluminum alloy strips are widely used in electrical appliances, hardware, construction and other industries. The composition of existing aluminum alloy strips is roughly the same. For example, the main components of existing aluminum alloy strips are Fe / Si, Cu, Mn, Mg , Zn, Ti and Al, etc., the aluminum alloy strip can be obtained by smelting, casting, cold rolling, longitudinal shearing, annealing and other operations of the raw materials of these components, but the content of the main components of the existing aluminum alloy There are obvious differences, and this kind of difference leads to the soft strength of the aluminum alloy strip produced. At the same time, the rare earth is ignored in the composition of the existing aluminum alloy...
