Embodiment Construction

[0011] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0012] An aluminum alloy of the present invention, the weight percentage of each group is as follows, manganese: 1%-2%, silicon: 2%-3.5%, iron: 0.5%-1.5%, copper: 0.1%-0.5%, zinc: 0.5% %-1%, chromium: 0.2%-1.5%, cerium: 1%-2%; the balance is aluminum and impurities with a content of ≤0.5%, and the components are fully proportioned.

[0013] In this embodiment, the preferred weight percentage of manganese is 1.5%. The silicon weight percentage is 3%. Iron is 1% by weight, copper is 0.3% by weight, zinc is 0.7% by weight, chromium is 1% by weight, and cerium is 1.5% by weight.

[0014] The aluminum alloy of the invention has reduced cracks, good elongation and greatly increased service life.

Abstract

The invention provides an aluminum alloy. The aluminum alloy comprises the following components in percentage by weight of 1-2% of manganese, 2-3.5% of silicon, 0.1-0.5% of iron, 0.1-0.5% of copper, 0.5-1% of zinc, 0.2-1.5% of chromium, 1-2% of cerium, and the balance of aluminum and impurities of which the content is less than or equal to 0.5%, and the components are sufficiently mixed. According to the aluminum alloy disclosed by the invention, the crackles are reduced, the elongation is good, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to an aluminum alloy. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. The existing aluminum alloy has poor elongation and short service life. Contents of the invention [0003] (1) Technical problems to be solved [0004] The problem to be solved by the present invention is to provide an aluminum alloy to overcome the defects of poor elongation and short service life in the prior art. [0005] (2) Technical solutions [0006] In order to solve the above technical problem, the present invention provides an aluminum alloy, the weight p...
