Definitions
- the invention relates to an aluminum alloy, a semi-finished product, a can, a method for producing a slug, a method for producing a can and to the use of an aluminum alloy.
- Aerosol cans made of aluminum or an aluminum alloy generally have a cylindrical can body, a can bottom that closes one end of the cylindrical can body, a can shoulder, a can neck at an opposite end of the can bottom, and a valve and a spray head.
- Such aerosol cans are typically produced by means of extrusion, in particular by means of backward extrusion or a combined forward and backward extrusion process.
- As a semi-finished product for the production of aerosol cans slugs several millimeters thick, punched out of aluminum or aluminum alloy strips, are used.
- the raw cans present after the extrusion are - in addition to further processing steps - usually subjected to a washing and cleaning step before the inside of the cans are provided with a lacquer coating (internal lacquer) in order to protect a filler from direct contact with the can wall.
- a lacquer coating internal lacquer
- the inner varnish is baked in a stoving oven.
- Other work steps include painting the exterior, printing and coating the outer surface of the raw can, as well as molding the aerosol can end contour.
- the cans should have an appropriate strength in order to offer a secure container to an ingredient under pressure.
- the cans should be light and therefore thin-walled.
- the strength properties of an aerosol can are determined to a large extent by the composition of a slug used to manufacture an aerosol can and in particular by its manufacturing process.
- Aluminum alloys are known, for example, from EP 1 064 413 B1, FR 2 457 328 A1, JP 2008169417 A, US 2006/0021415 A1 and US 2014/0298641 A1.
- Aerosol cans made from aluminum alloys generally have a higher strength and pressure resistance than pure aluminum.
- it is used - as is also the case with the use of pure aluminum - there is the problem that there is a drop in hardness and therefore also in strength during the manufacturing process of the can, in particular during the baking of an inner lacquer.
- the inner lacquer is stoved in a temperature range of 230 ° C to 250 ° C, which leads to a reduction in the strain hardening achieved during the extrusion process due to the recovery and recrystallization effects in the aluminum alloy.
- thicker wall thicknesses are typically chosen for the can in order to be able to meet the required technical properties and safety standards of the can. This applies in particular to their pressure resistance.
- a higher wall thickness is disadvantageous for economic reasons and for weight considerations and therefore from a handling point of view.
- the invention is based on the object of an aluminum alloy which is improved compared to the prior art, a semifinished product which is improved compared to the prior art, in particular a slug improved compared to the prior art, a can improved compared to the prior art, and a compared to the prior art to provide an improved process for the production of a slug, to provide a process for producing a can which is improved compared to the prior art, and to use an aluminum alloy which is improved compared to the prior art.
- the aluminum alloy is said to be particularly suitable for producing a can, preferably an aerosol can, with high strength and at the same time low can wall thickness and in particular with good forming properties.
- the invention solves this problem by providing an aluminum alloy with the features of independent claim 1, a semi-finished product or a can according to claim 10, a method for producing a slug according to claim 1 1, a method for producing a can according to claim 12 and a use an aluminum alloy according to claim 13.
- Preferred embodiments of the aluminum alloy are the subject of dependent claims 2 to 9. The wording of all claims is hereby made the content of the present description by express reference.
- the invention relates to an aluminum alloy, in particular for a slug, that is to say a round blank, and / or a can, preferably an aerosol can.
- the aluminum alloy consists of:
- the aluminum alloy can either be made of
- the proportions disclosed in the present invention in percent by weight (wt%), i.e. the so-called weight fractions relate to the total weight of the aluminum alloy.
- the term “slug” or “round blank” is intended to mean a disk, in particular a cylindrical disk, preferably a circular-cylindrical disk.
- the disk preferably has a very low height in relation to the diameter.
- the disk can have a height of 3 mm to 13 mm, in particular 4 mm to 10 mm, preferably 4.5 mm to 7 mm, and / or a diameter of 10 mm to 130 mm, in particular 20 mm to 80 mm, preferably 30 mm to 60 mm.
- the term “aerosol can” is to be understood as a can for spraying liquids or semi-liquid media in the form of an aerosol.
- the liquids or semi-liquid media can be, for example, a hairspray, a deodorant, a shaving foam, a color, a paint, a varnish, a lacquer, a furniture polish, an oil, a liquid soap, a resin, a paraffin liquid wax, natural rubber, a glue, a disinfectant, an impregnating agent, a cleaning agent, an organic liquid, an inorganic liquid, a liquid / semi-liquid food such as spray cream, a liquid / semi-liquid cosmetic product such as liquid / semi-liquid body care product or a liquid / semi-liquid pharmaceutical Trade product.
- the aerosol can can also be referred to as a spray can.
- the invention is based on the surprising finding that when an aluminum alloy according to the invention is used to produce a can, preferably an aerosol can, the recovery and recrystallization phase when an inner lacquer is baked into the can can be suppressed.
- the combination of the elements copper and chromium contained in the aluminum alloy according to the invention is responsible for this.
- cluster and / or precipitation hardening occurs at the temperatures used for baking an inner lacquer.
- metastable clusters and / or precipitates of the copper alloy element are formed, which lead to an increase in strength and thus counteract recrystallization and a consequent loss of strength.
- the dispersion hardening that occurs in the case of chromium during the baking of an inner lacquer is based on a very similar effect, but through larger dispersed chromium compounds.
- the larger dispersed chromium compounds can in particular be so-called dispersoids of the formula Al (Fe, Cr, Mn) Si.
- dispersoids of the formula AlFeSi are advantageously formed, which lead to an (additional) increase in strength through dispersion hardening.
- the addition of manganese ie the use of manganese for the production of the aluminum alloy, advantageously results in mixed crystal hardening, which (additionally) increases the strength of the aluminum alloy.
- the finest dispersoids of the formula AI (Fe, Cr, Mn) Si can form, which further increase the strength of the aluminum alloy.
- the manganese weight fraction provided according to the invention has on the one hand turned out to be sufficiently high to achieve an increase in the strength of the aluminum alloy. On the other hand, it has not proven to be too high in order not to increase the deformation resistance and in particular the risk of cracking too much. This is particularly advantageous when using the aluminum alloy for the production of cans such as aerosol cans.
- the addition of titanium ie the use of titanium to produce the aluminum alloy, advantageously results in grain refinement and fine grain hardening, which increase the strength and ductility of the aluminum alloy.
- the aluminum alloy according to the invention can thus be used to produce a can, preferably an aerosol can, with a higher strength than cans of the generic type.
- the higher strength in turn allows, with particular advantage, less use of material, as a result of which cans with a smaller wall thickness or thickness can be produced. This is advantageous both from an economic point of view and from a handling point of view (lower weight of the can).
- a further advantage is that the aluminum alloy according to the invention can be used to produce cans whose strength is high enough to achieve a desired reduction in the can wall thickness and the associated material savings, but on the other hand is not too high, so that the can is easily deformable is guaranteed. This is particularly advantageous when manufacturing cans with complex shapes, since otherwise there is a risk of the cans tearing open.
- the weight fraction of silicon is 0.08% by weight to 0.14% by weight, preferably 0.09% by weight to 0.13% by weight.
