Zusammenfassung:	The invention discloses a super-strong high-toughness corrosion-resistant aluminum alloy annular forge piece for spaceflight and a preparation method of the super-strong high-toughness corrosion-resistant aluminum alloy annular forge piece, relates to the preparation method of the super-strong high-toughness corrosion-resistant aluminum alloy annular forge piece for spaceflight, and aims at solving the problem that an existing aluminum alloy annular forge piece cannot meet the spaceflight use requirement. The aluminum alloy annular forge piece is prepared from smelting raw materials including Cu, Mg, Zn, Zr, Cr, Ti and Al through smelting, casting, homogenizing annealing, hot forging, quenching, cold compression and aging. The super-strong high-toughness corrosion-resistant aluminum alloy annular forge piece is produced through alloy component optimization, ingot casting quality control, a multi-stage homogenization treatment technology, a forging forming technology and a three-stage quenching and two-stage a
