Abstract
The effects of corrosive environments on aluminum-lithium-copper-(magnesium) alloys have been studied as they relate to the commercial airplane industry. It has been found that, in general, the alloys 2090 and 2091 exhibit equal or improved corrosion performance compared to the 2024 and 7075 alloys they are likely to replace. Cladding and coating systems have been shown to compare favorably with conventional alloys.
