Abstract (en)
[origin: EP0589807A1] Alloy of the 7000 series and a specific heat treatment with a view to the manufacture of hollow bodies under pressure and, in particular, of metal bottles for compressed gases. The alloy contains, in weight %: 6.25 </= Zn </= 8.0 Mn </= 0.20 1.2 </= Mg </= 2.2 Ti </= 0.05 1.7 </= Cu </= 2.8 0.10 </= Zr </= 0.25 others, each </= 0.05 Fe </= 0.20 '' total </= 0.15 Si+Fe </= 0.40 remainder: Al Cr </= 0.05. The final annealing is preferably performed in 3 stages: - 1st stage between 105 and 120 DEG C for 6 to 12 h - 2nd stage: between 170 and 190 DEG C for 0.5 to 20 h - 3rd stage: between 105 and 120 DEG C for 12 to 36 h.
