Definitions

  • the invention relates to an improved aluminium alloy and more particularly relates to an aluminum alloy which contains controlled amount of defined compound and is characterised by the combination of high extrudability and high corrosion resistance.
  • aluminium alloys are used in a number of applications, especially for tubing because of the extrudability of the alloys combined with high strength and relatively high weight.
  • aluminium alloys for use in heat exchangers or air conditioning condensers.
  • the alloy must have a good strength, a sufficient corrosion resistance and a good extrudability.
  • a typical aluminium alloy used in this application is AA 3102. Typically this alloy contains 0,15% by weight of Si, 0,20% by weight of Fe and 0,25% by weight of Mn.
  • aluminium alloy composition which exhibits superior corrosion resistance and improved extrudability.
  • the aluminium alloy of the present invention includes controlled amounts of iron, silicon, mangonese and zirconium.
  • the manganese content is limited to improve the extrudability of the alloy and to offset the effect of the zirconium alloying component which causes the flow stress of the aluminium alloy to be higher than alloys without the addition of zirconium.
  • alloy which contains manganese in an amount between 0.05 - 0.40% by weight.
  • an aluminium-based alloy consisting essentially of about 0,10-0,40% by weight of iron, about 0,05-0,25% by weight of silicon, about 0,05-0,2% by weight of zirconium, and the balance aluminium and incidental impurities, said aluminium-based alloy exhibiting high corrosion resistance and being capable of being extruded using a high tensile strenght.
  • the zirconium content is limited to an amount between 0.10 - 0.18% by weight, , more preferable between 0,15 - 0,18% by weight.
  • the alloy contains in addition 0,05 - 0,40% by weight of manganese.
  • the zirconium content is limited to an amount between 0,10 - 0.30% by weight, and more preferable the manganese content is limited to an amount between 0,20 - 0,25% by weight.
  • the chromium content is limited to an amount between 0,05 - 0,30% by weight, preferably between 0,08 - 0,10% by weight, and more prefarably between 0,08 - 0,10% by weight, the iron content is limited to 0,15 - 0,20% by weight and the silicium content is limited to 0,10 - 0,25% by weight.
  • compositions were selected for comparison purposes with a preferred invention alloy composition.
  • the two compositions are designated as alloy A and alloy B; alloy A being an average 3102-alloy as practically used in the extrusion of heat transfer components, such as multiple port extrusion tubes, alloy B corresponds to a composition as described in the US-A-5286316.
  • alloy I The preferred embodiment of the invention alloy is designated as alloy I, wheras onother alloy according to the invention in designation alloy II
  • SWAAT-test For determining the corrosion resistance of these alloys, use is made of the so-called SWAAT-test. This test was performed according to ASTM-standard G85-85 Annex A3, with alternating 30 minutes spray periods and 90 minutes soak periods at 98% humidity. The electrolyte is acidified, with acetic acid, artificial sea water with a pH of 2,8 to 3,0 and a composition according to ASTM standard D1141. The temperature is kept at 49°C. The test was run in a Liebisch KTS-2000 salt spray chamber.
  • samples from the different alloys A, B, I and II were taken out of the chamber at the following moments : after 2 days (1); 6 days (2); 12 days (3); and 23 days (4).
  • the materials were then cleaned in water and subsequently cleaned in chrominium-phosphoric acid.
  • alloy I and II according to the invention has superior corrosion resistance as companies with the alloy A, but alloy II has somewhat lesser corrosion resistance as compared with the alloy B.
  • the die Force and the Extrusion Force have been measured by means of pression transdueers . mounted on the press, after which the obtained values have been recalculated in order to express the obtained values in Tons.
  • the alloy I and II according to the invention has improved mechanical properties compared with the alloys A and B, whereas the extrudability is maintained at an acceptable level.
