Abstract (en)
An Al-Mg-Si based aluminum alloy extrusion having large strength, absorbable impact energy and resistance against compressing cracking, wherein the average size of Mg2Si precipitation in the Ä1 0 0Ü and Ä0 1 0Ü directions of the (1 0 0) plane inside grains is 20 nm or more, the distribution density of the Mg2Si precipitation in the Ä0 0 1Ü direction of the (1 0 0) plane is 100 or more per mu m<2>, and the size of precipitations on grain boundaries is 1000 nm or less. Alternatively, in the Al-Mg-Si based aluminum alloy extrusion, a tensile strength obtained from a tensile test performed at a strain rate of 1000 per second is from 150 to 400 N/mm<2> (both inclusive).
