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.
