Definitions

  • the invention relates to an aluminum-based alloy containing Si and Mg as main alloying elements, having high mechanical characteristics and intended mainly for the manufacture of spun or die-formed products.
  • the known alloys of this type are alloys 6082 or X6013, according to the designations of the Aluminum Association, treated in state T6, the analyzes of which (% by weight) and the typical mechanical characteristics are as follows:
  • the latter element is advantageously between 0.3 and 0.6%.
  • the hot transformation temperature is maintained above 450 ° C.
  • a restorative annealing in a temperature range between 250 and 280 ° C for periods ranging from 1 to 10 hours approximately .
  • the billets are intended for spinning, it is preferable to make them undergo a homogenization between 500 and 580 ° C. for durations going from 3h to 10h in order to improve their aptitude for this hot transformation.
  • FIG. 1 representing the stamped part of Examples 2 and 3 on which the dimensions in mm appear.
  • the known alloys 6082 and X6013, as well as alloys 2 to 4 according to the invention, were produced in semi-continuous casting in the form of 0 120 mm billets, homogenized 24 h at 530 ° C., peeled at 0 96 mm, spun live at 470 ° C approx. in flats 60 x 10 mm, these are then dissolved at 540 ° C for 2 hours, soaked in cold water and returned to 175 ° C for 8 hours.
  • the alloys according to the invention reach the desired characteristics, while the known alloys 6082 and X6013 do not achieve them.
  • the products are mainly intended for spinning in the form of bars or profiles for example, and for stamping, but it is not excluded to laminate them in sheets, strips or to draw them, provided that these operations are carried out so as not to induce a notable crystallization.
