摘要： The invention relates to hollow bodies for gas under pressure manufactured from an aluminum alloy containing Zn, Cu and Mg as principal alloying elements and intended in particular for the production of metal bottles for pressurized gas. The hollow bodies are manufactured from an alloy consisting essentially of (in % by weight):______________________________________ 6.25 .ltoreq. Zn .ltoreq. 8.0 Mn .ltoreq. 0.20 1.2 .ltoreq. Mg .ltoreq. 1.95 Zr .ltoreq. 0.05 1.7 .ltoreq. Cu .ltoreq. 2.8 Ti .ltoreq. 0.05 0.15 .ltoreq. Cr .ltoreq. 0.28 Others each .ltoreq.0.05 Fe .ltoreq. 0.20 Others total .ltoreq.0.15 Si + Fe .ltoreq. 0.40 Balance Al. ______________________________________ The alloy in state T73 complies with the very severe technical requirements in respect of strength and ductility which are imposed in relation to use for hollow bodies under pressure.
