Definitions

  • the present invention relates to a method for manufacturing hollow bodies under pressure such as tanks, bottles or the like, in aluminum alloys, type 7475 (according to the designation of the Aluminum Association) and having both high strength and toughness high.
  • operations 3) and 4) could be replaced by a single operation of cold spinning.
  • the Fe content is preferably kept below 0.08%, and the Fe + Si content ⁇ 0.18%.
  • the pieces were spun by reverse spinning and hot drawn at 400 ° C ⁇ 10 ° C, then turned to 0 155 mm and annealed at 420 ° C, maintained for 4 hours. After pickling, they were cold drawn with an elongation (S - s) / s of 13.5% and cut to length.
  • the open part of the case thus obtained is then warned at 400 ° C, then pierced and cut.
  • the bottle was finished by machining the neck and fitting the ring.
