Abstract
The invention concerns an extruded profile made of an Al-Mg-Si aluminium alloy designed for industrial automotive applications. extruded profile comprising an Al-Mg-Si alloy containing, in wt.%, Si 0.3 - 1.2, Mg 0.3-1.1, Cu ≤ 0.85, Mn 0.05 - 0.80, Cr 0.01 - 0.20, Fe 0.26 - 0.64, preferably Fe 0.30 - 0.60, Zn 0.15 - 1.0, V ≤ 0.10, Ti ≤ 0.10, Zr ≤ 0.15, other elements < 0.05 each and < 0.15 total, rest aluminium, wherein Free-Si ≥ 0.50 with Free-Si = Si - 0,3 * (Fe + Mn), wherein Si, Fe, and Mn represent the silicon, iron, and manganese content in wt.%. The invention also relates to the manufacturing process to obtain such extruded profile.
