7A04 aluminum tube belongs to Al-Zn-Mg-Cu series ultra-high-strength aluminum alloy, also known as super-hard aluminum. It is a relatively mature and widely used alloy in super-hard aluminum. Its strength is high, the heat treatment strengthening effect is good, and the plasticity is medium in the annealed and newly quenched state. It is usually used in the artificial aging state of quenching. At this time, the strength is much higher than that of ordinary hard aluminum, but the plasticity is low
