Abstract

The invention discloses a high-elongation deformation rare earth aluminum alloy and a manufacturing method, and mainly relates to the field of aluminum alloys. The alloy comprises the following components in percentage by weight: 5-7% of Zn; 2-3% of Mg; 1-2% of Cu; 0.3% to 0.6% of Y; less than or equal to 0.15% of inevitable impurities; and the balance of aluminum. The method has the beneficial effect that the wrought aluminum alloy which does not contain rare earth and is tough and tough is prepared.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to a high-elongation deformed aluminum alloy and a manufacturing method thereof. Background technique [0002] The new energy vehicle uses aluminum alloy as the raw material and solves the one-time molding of complex surface parts through the extrusion process, and at the same time achieves the effect of light weight. On the other hand, the profiles extruded into complex cross-sections by selecting different aluminum alloy grades bear the load-bearing and impact-absorbing energy effects on the vehicle. [0003] As the metal with the second largest reserves in the world, aluminum alloy provides a good solution for OEMs to achieve lightweight design targets. As we all know, the density of aluminum alloy is 2.7kg / m3, which is only 1 / 3 of that of iron. Aluminum has a face-centered cubic structure, so it has good plasticity, is easy to form and process, and has good corrosion resistance. ...
