Family: Aluminum Alloy
Copper Alloy (Al-Cu). AA designation 2060.
Overview
Engineered for demanding airframe duty, AA 2060 is an advanced aluminium–copper–lithium alloy (about 3.5–4.5% Cu, 0.6–1.0% Li) that improves on earlier Al–Li grades in damage tolerance and corrosion resistance. It trims density by roughly 4–5% against 2024 while holding or bettering fatigue crack-growth resistance. The alloy is applied to fuselage skin panels, aircraft seat tracks, and airframe structural members where light weight must not compromise durability.

Description
AA 2060 is an advanced aluminum-copper-lithium alloy developed for aerospace applications, offering improved damage tolerance and corrosion resistance compared to earlier Al-Li alloys. It contains approximately 3.5–4.5% copper and 0.6–1.0% lithium, providing a density reduction of about 4–5% over 2024 with maintained or improved fatigue crack growth resistance. Primary uses include fuselage skin panels, aircraft seat tracks, and airframe structural components.
