Description
AA 7005 is a medium-strength weldable aluminum-zinc-magnesium alloy (~4.0–5.0% Zn, 1.0–1.8% Mg) with additions of manganese and zirconium, notable for recovering its full T53 temper strength through natural aging after welding without separate heat treatment. It offers good extrusion characteristics and excellent corrosion resistance in marine environments. Applications include bicycle frames, sporting goods, railroad car structures, and welded marine structures.
