Abstract
A 7000-series aluminum alloy hollow extruded material formed by porthole extrusion contains Zn: 3.0 to 8.0 mass %, Mg: 0.4 to 2.0 mass %, Cu: 0.05 to 2.0 mass %, Si: 0.3 mass % or less, Fe: 0.35 mass % or less, and one or more of Mn, Cr, and Zr: 0.10 mass % or less in total, with the balance being Al and unavoidable impurities. The aluminum alloy hollow extruded material has a recrystallized structure throughout the cross-section. In the case of pipe expansion by electro-magnetic forming, excellent pipe expansion formability is obtained.
