กลุ่ม: Aluminum Alloy
Zinc Alloy (Al-Zn). AA designation 7005.
Overview
AA 7005 is a medium-strength, weldable aluminium–zinc–magnesium alloy (about 4.0–5.0% Zn, 1.0–1.8% Mg) with manganese and zirconium additions, notable for recovering its full T53 temper strength by natural ageing after welding, without a separate heat treatment. It extrudes well and resists corrosion in marine environments. These traits make it popular for bicycle frames, sporting goods, railroad-car structures, and welded marine fabrications.

คำอธิบาย
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.
