Definitions
- the invention relates to the field of aluminum alloys, and more particularly those intended for the manufacture of aerosol cans.
- the pins are obtained from strip by hot rolling, then cold rolling.
- the impact-spun boxes are then typically degreased, varnished internally and / or printed externally, treated in an oven so as to bake the inks and dry the varnishes, and finally conified.
- the aluminum alloy intended for the manufacture of aerosol cans obtained by impact spinning of pions of said alloy or by impact spinning of these pions followed by drawing, comprises copper and manganese, the 2 composition in Cu and Mn is located inside the polygon ABCD defined, in a system of coordinate axes with the content of Mn (% by weight) on the abscissa and that of Cu (% by weight) on the ordinate, by the coordinates of points A, B, C and D: abscissa (Mn%) ordered (Cu%) A 0.075 0.65
- Mn contents they above all aim to reduce the softening of the metal during the annealing of lacquers and varnishes of aerosol cans.
- the tests carried out by the applicant have shown that an Mn content situated below the limit imposed by the straight line AD would lead to a too coarse-grained pawn, ultimately leading to the formation of folds during the conification of the final aerosol.
- an Mn content situated below the limit imposed by the straight line AD would also lead to an aerosol with insufficient mechanical characteristics, in particular taking into account the need to reduce the thickness of the walls of aerosol housings to reduce notably the metal costs
- the figure 1 i represents the diagram of the compositions in the plane Ox, y, where the abscissa Ox represents the weight concentration in Mn of the alloy of Al, and where the ordinate Oy represents the weight percentage in Cu of Al alloy
- the polygon ABCD delimits the domain of the Mn and Cu compositions of the aluminum alloys according to the invention
- FIG. 2 is a qualitative illustration of the variation of the mechanical characteristics Rm (in oi given), as a function of the height H (on the abscissa) of the aerosol casing obtained for the same starting pawn, on the left part A of the diagram , as a function of the heat treatment time for baking varnishes and inks (on the abscissa), on the right-hand side B
- Curve I corresponds to the impact spinning process, while curve II corresponds to a first step F ⁇ of impact spinning, followed by a second stretching step En
- Piefeience of the aluminum alloy according to the invention has a composition of Cu and Mn is located has the intei ieui EFGH of polygon defined by the coordinates of points
- the alloy compositions according to the invention are particularly advantageous when, on the one hand the pins (4) are obtained from continuous casting strip (3) as illustrated in FIG. 3 and when, on the other hand, the pins are transformed into aerosol housings by a spinning step by shock, followed by a second stretching step as shown diagrammatically in FIGS. 4a to 4c
- alloys according to the invention are less sensitive than the standard alloys or the alloys outside the invention, to the effects of the heat treatment (part B of FIG. 2) and to the reduction in mechanical characteristics which results from this treatment.
- 1 invention peimet d obtained aerosol cans having, as desired, either better mechanical characteristics and therefore resistance to higher internal pressure, or less wall thickness, which corresponds to a saving in metal
- the alloy according to the invention can, in addition to the elements Cu and IVIn, comprise other elements: 0.005 to 0.05% by weight of Ti, from 0.2 to 0.5% by weight of Fe, and less than 0.2
- titanium is aimed at obtaining relatively fine-grained casting tape (3).
- the elements Fe and Si they are most often impurities from aluminum.
- the Fe content results from the fact that this element, at a content greater than 0.2% by weight, plays a role in reducing the size of the grains, while beyond a content of 0.5% in weight, its effect is negative, because it annihilates the effect of manganese by trapping this element.
- Silicon is a simple impurity, the content of which must be kept below 0.2% by weight, otherwise the solubility of manganese is lowered, which leads in particular to larger grains.
- a second object of the invention relates to the use of the alloys according to the invention for obtaining aerosol cans produced by shock spinning of pawns (4) of said alloy, said pawns being obtained from strip continuously cast .
- this second object relates to the use of the alloys according to the invention for obtaining aerosol cans produced by shock impact spinning (4) of said alloy and subsequent drawing of the blank (5) obtained, said pins being obtained from continuous casting tape.
- the selection of alloys according to the present invention is particularly suitable in the case of pins obtained from continuously cast strip, and more particularly advantageous when these pins are transformed into aerosol cans by impact spinning followed by 'a stretching step.
- a third object of the invention is constituted by the aerosol canisters of an alloy according to the invention, obtained by impact spinning of pins (4) of said alloy, said pins being obtained from continuously cast strip.
- this third object is constituted by aerosol canisters made of an alloy according to the invention, obtained by impact spinning of pawns of said alloy followed by at least one drawing step, said pawns being obtained from cast strip. continuously.
- Pawns were produced in different aluminum alloys, as well as the corresponding drawn spun housings.
- the boxes obtained have the following dimensions:
Landscapes

- Engineering & Computer Science (AREA)
- Materials Engineering (AREA)
- Mechanical Engineering (AREA)
- Metallurgy (AREA)
- Organic Chemistry (AREA)
- Containers And Packaging Bodies Having A Special Means To Remove Contents (AREA)
