Abstract:
An aluminum alloy includes, in weight percent, 0.70-0.85 Si, 0.14-0.25 Fe, 0.25-0.35 Cu, 0.02-0.08 Mn, 0.75-0.90 Mg, 0.04-0.08 Cr, 0.05 max Zn, and 0.04 max Ti, the balance being aluminum and unavoidable impurities. The minimum Mn content may be 0.03 wt. %, and/or the maximum Mn content may be 0.06 wt. %, in various configurations. The alloy may be suitable for extruding, and may be formed into an extruded alloy product.
