Al-Li alloys can provide reduced weight and increased stiffness as replacements for conventional aluminum alloy aircraft components. A study was conducted to compare the performance of 2090 Al-Li and 7075 Al alloys in-service on Navy aircraft, during shipboard exposure and in laboratory accelerated tests. Results from this investigation indicated that no additional maintenance was required during in-service exposure and that the corrosion behavior of the two alloys in laboratory tests and during shipboard exposure was comparable.
