Abstract

A wrought aluminum alloy comprises 0.5 to 10 wt% Mg, 0 to 0.35 wt% Cr, at least 0.0005 wt% Sr, less than 1 wt% Fe, 3.5 wt% max. Zn, 1 wt% max. Cu, 0.3 wt% max. Ti, the remainder aluminum and incidental impurities, and wherein the alloy further comprises either: (a) 0.1 to 1.6 wt% Mn and 1 wt% max. Si, and the product has at least one intermetallic phase of the type containing Al-Fe-Si, Al-Fe-Mn and Al- Fe-Mn-Si, wherein at least one of such phases is refined; or (b) 0.3 wt% max. Mn and 0.3 wt% max. free Si, and the product has an intermetallic phase of the type containing Al-Fe in a refined condition. The product may be used as the substrate for a memory disc, or, when anodised, as decorative trim for motor vehicles.
