Abstract

The invention discloses a nano-aluminum profile and a preparation method thereof. The nano-aluminum profile is an Al-Mg-Si alloy system, and the alloy ingredients comprise Al, Mg, Si, Cu and Sm. The mass percent of Fe is less than or equal to 0.33%. The mass ratio of Mg / Si is 1.2-1.4; and the total mass percent of Mg and Si is 1.2-2.0%. In the process of preparing the nano-aluminum profile, added Cu is nano CU. On the aspect of the Al-Mg-Si aluminum alloy material modification technique, the nano-aluminum profile increases the extrusion speed, reduces the energy consumption in homogenization and improves the mechanical performance of the profile. Various nano metals are added in an Al-Mg-Si aluminum alloy material, and the microstructure and the comprehensive process performance of the Al-Mg-Si aluminum alloy material are improved, so that the extrusion processing performance, the mechanical performance and the corrosion resistance performance of the profile are improved.
