Abstract

The invention discloses an aluminium alloy. The aluminium alloy comprises the following components in percentage by mass: 5-7% of magnesium, 2-6% of silicon, 3-3.4% of iron, 2.6-3.6% of nodular cast iron, 0.5-0.8% of titanium, 2-9% of nickel chromium alloy and balance of aluminium. The invention also provides an aluminium alloy profile prepared from the aluminium alloy. The aluminium alloy and the aluminium alloy profile disclosed by the invention have the beneficial effects that strength is enhanced by 2-3 times compared with that of the previous aluminium alloy, oxide treatment is carried out on the surface of the aluminium alloy profile by taking the aluminium alloy as basis, higher-strength welding requirement can be met, and an application field is wide.

Description

technical field [0001] The invention relates to the field of alloys, in particular to an aluminum alloy and an aluminum alloy profile. Background technique [0002] Aluminum alloy is an alloy composed of aluminum as a matrix element and one or more alloying elements. 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 science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. However, most of the existing aluminum alloys have poor strength and cannot meet the high-strength welding requirements. Contents of the invention [0003] The object of the present invention is to provide a high-strength aluminum alloy to address the above-mentione...
