The invention discloses an Al-Mg-Si alloy suitable for a complex section and a preparation method and application of the Al-Mg-Si alloy. Relates to the technical field of aluminum alloy. The Al-Mg-Si alloy comprises the following components in percentage by mass: 0.6%-0.9% of Mg, 0.6%-0.8% of Si, less than or equal to 0.05% of Cu, less than or equal to 0.15% of Fe, 0.10%-0.30% of Mn, less than or equal to 0.05% of Ti and 97.5%-99.0% of Al. According to the Al-Mg-Si alloy disclosed by the invention, reasonable component matching and reasonable dosage matching are adopted, so that when the Al-Mg-Si alloy is prepared, an extruded profile with the wall thickness of 2.0-15.0 can be prepared at an extremely high extrusion speed, and compared with the prior art, the extrusion speed is increased by 114%. 本发明公开了一种适用于复杂截面的Al-Mg-Si合金及其制备方法与应用。涉及铝合金技术领域。上述Al-Mg-Si合金，按质量百分比计，包括以下组分：Mg：0.6％-0.9％，Si：0.6％-0.8％，Cu：≤0.05％，Fe：≤0.15％，Mn：0.10％-0.30％，Ti：≤0.05％，Al：97.5％-99.0％。本发明的Al-Mg-Si合金，由于采用了合理的组分搭配，以及合理的用量搭配，使得在制备Al-Mg-Si合金时候，
