Definitions

  • the present invention relates to the use of zinc alloys as Zinc for strips and sheets.
  • strips and sheets made of alloyed zinc for building purposes contain zinc as well a content of 99.99% 0.005 to 0.05% by weight aluminum and additions of 0.05 up to 0.2% by weight of titanium and copper.
  • This alloy is described for example in DE 17 58 498 and corresponds to DIN 17 770, part 1.
  • This material is generally produced using the casting-rolling process, in a continuous process (melting - Casting - rolling - winding) strips are produced in predetermined thicknesses, which are then cut into narrow strips or sheets on scissor lines.
  • This material is very stable in the atmosphere.
  • the surface reacts initially with the formation of zinc oxide with the oxygen in the air.
  • By The action of water then forms zinc hydroxide, which by reaction with the air's carbon dioxide into a dense, firmly adhering and water-insoluble Base layer of basic zinc carbonate is converted.
  • This protective layer is also responsible for the high corrosion resistance of such strips and Panel.
  • DE-715 511 C describes the use of a zinc alloy with 6 to 15% by weight aluminum for deep-drawing ticks.
  • the task of making strips and sheets of alloyed zinc available as construction zinc positions that meet even higher requirements are now solved by: all the aluminum content is set to 8 to 15% by weight with further alloy components as defined in A1.
  • the alloy contains 0.002 to 0.4 wt .-% Ti and / or 3 to 100 ppm boron and / or 3 to 50 ppm magnesium. Further improvements are achieved by alloying 0.002 to 0.04% by weight indium and / or 0.002 to 0.04% by weight Calcium and / or 0.05 to 0.8% by weight Manganese. Copper, iron and lead should only be included in the amounts that are considered Contamination of the zinc and aluminum are inevitable. Improvements in the properties are possible according to claim 1 by 3 to 100 ppm carbon, 2 to 500 ppm vanadium, 2 to 500 ppm Silicon and / or 2 to 500 ppm nickel.
  • the improved properties of the alloys used according to the invention result from comparative corrosion tests with the salt spray test according to DIN 500 21 ss (aging 7 and 14 days) and the condensation / SO 2 test according to DIN 50 018 KFW 0.2 s (aging 22 cycles). After aging, the changes in mass and the visual appearance of the corrosion of the sheets are determined.
  • the preferred alloyed elements are indium, calcium, titanium and manganese mainly affect the mechanical properties, but also improve also the corrosion behavior.
  • Impurities of more than 0.1% by weight copper and more than 0.1% by weight iron lead to deteriorated mechanical properties and in particular reinforce intergranular corrosion. These metals and other contaminants should thus only be present in the usual unavoidable amounts.
  • the strips and sheets that can be used as building zinc are made by the usual casting-rolling process manufactured. In principle, all can be considered as zinc qualities Zinc grades according to EN 1179 are used, with the Z1 grade preferred is because it contains relatively little lead, iron and copper.
  • Aluminum as an alloy component is preferably used in the Qualities according to EN 576.
