Abstract: An aluminium alloy extruded product obtained by casting a billet from a 6xxx aluminium alloy comprising: Si: 0.3-1.5 wt. %; Fe: 0.1-0.3 wt. %; Mg: 0.3-1.5 wt. %; Cu<1.5 wt. %; Mn<1.0%; Zr<0.2 wt. %; Cr<0.4 wt. %; Zn<0.1 wt. %; Ti<0.2 wt. %, V<0.2 wt. %, the rest being aluminium and inevitable impurities; Wherein an ageing treatment is applied such that the product presents an excellent compromise between strength and crashability, with a yield strength Rp0.2 higher than 240 MPa, preferably higher than 280 MPa and when axially compressed, the profile presents a regularly folded surface having cracks with a maximal length of 10 mm, preferably less than 5 mm.

Abstract: An armor component produced from a 7xxx series aluminum alloy, wherein the aluminum alloy consists essentially of: 8.4 wt. %?Zn?10.5 wt. %; 1.3 wt. %?Mg?2 wt. %; 1.2 wt. %?Cu?2 wt. %; at least one dispersoid forming element with a total dispersoid forming element content higher than 0.05 wt. %; the remainder substantially aluminum, incidental elements and impurities.

Abstract: The invention relates to a manufacturing process for an aluminum block of at least 250 mm thick designed for the manufacture of elements for vacuum chambers in which the following operations are carried out successively: an alloy block is cast by semi-continuous casting, the composition of this block in weight % being: Si 0.5-1.5; Mg: 0.5-1.5; Fe<0.3; Cu<0.2; Mn<0.8; Cr<0.10; Ti<0.15, other elements <0.05 each and <0.15 in total, the rest aluminum; solution heat treatment is performed at a temperature ranging between 450 and 560° C. directly on the cast block and optionally homogenized; the block that has undergone solution heat treatment is quenched at a cooling speed between the solution heat treatment temperature and 200° C. of at least 200° C./h; the block quenched and optionally stress-relieved is artificially aged.
