Abstract
Aluminum-zinc-magnesium-scandium alloys containing controlled amounts of alloying additions such as silver and tin are disclosed. The presence of Ag and/or Sn alloying additions improves fabrication characteristics of the alloys, such as the ability to be extruded at high temperatures and very high extrusion rates. The Al—Zn—Mg—Sc alloys may optionally include other alloying additions such as Cu, Mn, Zr, Ti and the like. The alloys possess good properties such as relatively high strength and excellent corrosion resistance. The alloys may be fabricated into various product forms such as extrusions, forgings, plate, sheet and weldments.
