Abstract The characteristics of 6061 aluminum alloy sheet and its application development in airplane were introduced,
meanwhile considering using requirement of aircraft, the problem of application in airplane were analyzed. The
welded property, formability and compression property were tested. The results show that joint efficiency of the domestic
joint exceeds 90%, which is corresponding to traditional corrosion-resisting aluminum alloy, and tensile properties are
higher than that of imported material; The producing of large size thin-walled tube is feasible by deep drawing technology
under the conditions of reasonable controlling parameters; The dimension of the thin-walled tube can meet the requirement
indicated at drawing completely and conform to the requirements of the drawings for the aircraft, whose pressure-resistant
properties can satisfy the use requirement, but the stability is slightly lower than those imported material.
