摘　　要：6A02铝合金薄壁管材生产中常存在力学性能不合格问题,对6A02铝合金薄壁管材采用不同的退火温度和退火保温时间进行试验,确定了该种管材合理的退火制度,使其力学性能满足了用户的要求。Unqualified mechanical properties often occurred in production of thin-wall tubes of 6A02 aluminum alloy. A reasonable annealing system for thin wall tubes of 6A02 aluminum alloy was finally determined by testing different annealing temperatures and annea- ling time, and mechanical properties could meet the requirements of the users at last.

关 键 词：6A02铝合金 薄壁管材 力学性能 退火温度 退火保温时间
