Definitions

  • aerosol cans are manufactured either from pure aluminium or from aluminium alloys.
  • 1000-series aluminium according to the European standard EN 573-3 is mostly used.
  • the most common aluminium grades are EN AW 1050A having the minimum Al content of Al 99.5% and EN AW 1070A having the minimum Al content of 99.7%.
  • aerosol cans are mostly made of 3000-series aluminium alloys according to the European standard EN 573-3.
  • the most common aluminium alloy grades are EN AW 3102 having the Mn content of approximately 0.3% and EN AW 3207 having the Mn content of approximately 0.6%.
  • aluminium and its alloys are mostly supplied in the form of slugs.
  • Such slugs are manufactured in a continuous two-phase process comprising the following steps.
  • the method of manufacturing aerosol cans can be described as follows:
  • Aluminium alloys EN AW 3102 and EN AW 3207 offer enhanced mechanical properties (strength) and hence better rigidity and pressure resistance of finished aerosol cans. Nevertheless, the mechanical properties of these materials are changed when the cans pass through a curing oven in which polymerization of the inner varnish layer takes place.
  • the curing (polymerization) temperatures of the inner varnish layers range between 210 and 255°C, the respective curing process lasting about 10 minutes. Under such temperatures, partial annealing of the can bodies occurs causing the mechanical strength of the same to decrease.
  • Fig. 1 shows the temperature dependences of the strengths of the new alloys in comparison with those of standard alloys by means of a graphical representation.
  • the subject matter of the present invention is a new, modified heat resistant aluminium based alloy provided for eliminating the effect of weakening the material of the cans passing through a curing oven.
  • the desired enhancement of the mechanical properties of aerosol cans is achieved in comparison with standard (conventionally used) materials, along with the reduction of the wall thickness and increase of the pressure resistance of the same.
  • the above favourable effect is achieved by adding an anti-recrystallization admixture formed by Zr (zirconium) for the purpose of modifying the composition of aluminium alloys falling under the EN AW 3207 standard.
  • the alloy according to the invention has new chemical composition with added Zr, the proportion of the new constituent ranging between 0.10 and 0.15% by weight.
  • the addition of Zr gives rise to completely new alloy which cannot be categorized in the existing classes according to the standard EN 573-3. Therefore, the new alloys will be referred to as MC alloys hereinafter, namely MC4 (EN AW 3207 + Zr).
  • the composition of the new alloy (in percent by weight) is as follows:
  • the new alloys were compared with the known, commonly used materials.
  • the outcome is graphically represented in Fig. 1 where the first standard material according to EN AW 1050A, herein specifically referred to as alloy A5, is compared with the new alloy MC1_A which is not subject of this application. and the second standard material according to EN AW 3102, herein specifically referred to as alloy A3Mn, is compared with the new alloy MC4_A containing the added anti-recrystallization constituent Zr.
  • the cans which were made of the above materials under the same technological conditions, had identical wall specifications.
  • Alloy A3Mn (aluminium alloy according to EN AW 3102) having the following chemical composition in percent by weight:
  • Table 1 shows the mechanical properties of the cans made of the above materials. During the comparison, the values of the tensile strength (Rm) of the cans measured before and after the curing oven, in which the inner varnish layer was polymerized, were evaluated. Moreover, the hardness (HB) of the input semifinished products (slugs) was measured.
  • aluminium alloys A3Mn and MC3_A show that the value of the tensile strength of the latter alloy was by 27.1 MPa higher after the passage through the polymerization oven under the temperature of 255°C.
  • the main advantages of the new alloys MC1, MC3 and MC4 particularly include:
