Abstract (en)
Aluminium alloy for shaped elements of vehicles and the like, which comprises from 0.25 to 0.35% of Si, from 0.20 to 0.30% of Fe; from 0.85 to 1.1% of Mg, from 0.10 to 0.25% of Cu; other elements, as impurities, each below 0.1%, in the aggregate below 0.2%; the balance to 100% being Al. A process for manufacturing shaped elements of vehicles starting from a cast body of said alloy, which is homogenized at 540-580 DEG C and then worked to obtain sheets (or the like), which are then subjected to a solution heat-treatment at 525-535 DEG C followed by hardening and natural ageing to state T4; said sheets are then formed by means of dies to shaped elements, which, at last, are subjected to artificial ageing at 180-220 DEG C.
