Definitions

  • the invention relates to an AI alloy which can be used for the manufacture of bottles. of metal for compressed gases.
  • the modification of the chemical composition on the one hand and the final heat treatment on the other improve the burst characteristics (facies of the tear) while maintaining the level of mechanical characteristics and resistance to corrosion under stress required.
  • the alloys used according to the invention have the following weight composition (in%): 6.25 ⁇ Zn ⁇ 8.0 1.2 ⁇ Mg ⁇ 2.2 1.7 ⁇ Cu ⁇ 2.8 0.10 ⁇ Zr ⁇ 0.25 Cr ⁇ 0.05 Fe ⁇ 0.20 Fe + Si ⁇ 0.40 Mn ⁇ 0.20 Ti ⁇ 0.05 Others each ⁇ 0.05 total ⁇ 0.15 Rest: Al
  • the Mg content is preferably kept below 2%, and even 1.95%, and the Zr content is preferably between 0.10 and 0.18%, the contents in Fe + Si being ⁇ 0.25% with Fe ⁇ 0.12%, an Mn content ⁇ 0.10% and / or the Zn content ⁇ 6.75.
  • the manufacturing and control process are similar to those described in EP-A-0257167, but preferably the treatment of final income type T73 is replaced by an income in 3 stages, the 1st stage being carried out between 105 and 120 °. C for 6 to 12 h, the 2nd step being carried out between 170 and 190 ° C for 0.5 to 20 h and the 3rd step being carried out between 105 and 120 ° C, for 12 to 36 h.
  • These steps can be carried out continuously or discontinuously (return to ambient temperature between each of them or some of them).
  • the durations and temperatures actually used are chosen by a person skilled in the art so as to obtain both a high electrical conductivity (corresponding to good resistance to corrosion under tension) and a high elastic limit.
  • Example 1 Replacement of Cr by Zr for two-phase income type T73.
  • the following example shows the gain that can be obtained by performing a returned in three stages to the bottles manufactured in alloy 2 according to the range of the previous example.
