Abstract

The invention discloses an Al-Mg-Si aluminum alloy and an extrusion method for a sectional bar of the Al-Mg-Si aluminum alloy. The Al-Mg-Si aluminum alloy comprises, by weight percent, 0.9%-1.25% of Mg, 0.5%-0.9% of Si, 0.2%-0.42% of Cu, smaller than or equal to 0.6% of Fe and 0.07%-0.35% of Cr and further comprises one or more elements of smaller than or equal to 0.15% of Mn, smaller than or equal to 0.22% of Zn, smaller than or equal to 0.15% of Ti, smaller than or equal to 0.05% of V, smaller than or equal to 0.5% of Hf, smaller than or equal to 0.25% of Sc, smaller than or equal to 1.0% of Ag and the balance Al. The aluminum alloy with the high mechanical performance is obtained by optimizing alloy components, the content of the alloy components and the sectional bar extrusion technology, and the production efficiency is effectively improved. The problems that in the prior art, conventional aluminum for transportation is low in strength and poor in ductility, the control range of the sectional bar extrusion technology link is wide, stability is poor, online quenching control difficulty is large, quenching uniformity is poor, and the production efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an extrusion method of Al-Mg-Si aluminum alloys and profiles thereof. Background technique [0002] Al-Mg-Si medium-strength aluminum alloy has the advantages of moderate strength, excellent welding performance, and light weight, and has been widely used in transportation and other fields. However, since Al-Mg-Si aluminum alloys have a wide range of optional Mg and Si content, and different Mg and Si content ratios often cause different alloy strengthening effects, so choosing a reasonable Mg and Si component content has a significant impact on Al-Mg- The strength, elongation and other properties of Si aluminum alloy have a great influence. At the same time, the profile extrusion process of aluminum alloy also has a huge impact on its performance. Factors such as too low quenching temperature or uneven temperature during quenching can have a great impact on the stability...
