The high cycle fatigue and the fatigue crack propagation behaviour of the new Al‐Li alloy 8090 were evaluated on 25 mm plate material and compared to the conventional high strength Al alloy 2024. The investigation covered changes of test direction, R‐ratio and environment. The results revealed that for most conditions the Al‐Li alloy proved to be equivalent or better than the conventional Al alloy.
