Abstract

The invention discloses aluminum alloy with high plasticity. The aluminum alloy comprises the following elements in percentage by weight: 50.8 to 56.9 percent of manganese, 29 to 30.5 percent of aluminum, 2.4 to 3.5 percent of magnesium, 3.1 to 4.1 percent of copper, 5.2 to 6.1 percent of chromium, 3.3 to 4.8 percent of molybdenum and 0.1 to 0.2 percent of other inevitable impurities. The aluminum alloy with the high plasticity has the advantages of high corrosion resistance, welding performance and plasticity.

Description

technical field [0001] The invention relates to an aluminum alloy, in particular to an aluminum alloy with good plasticity. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry. It 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, aluminum The demand for alloy welded structural parts is increasing day by day, so that the research on the weldability of aluminum alloys is also in-depth. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots of research. [0003] The density of pure aluminum is small (ρ=2.7g / cm3), about 1 / 3 of that of...
