Definitions

  • the present invention is directed to a group of corrosion resistant and extrudable aluminium alloys with improved elevated temperature strenght, especially to a AA3000 series type aluminium alloy including controlled amounts of titanium, vanadium and zirconium for improved extrudability and/or drawability.
  • aluminium is well recognized for its corrosion resistance.
  • AA1000 series aluminium alloys are often selected where corrosion resistance is needed.
  • AA1000 series alloys have been replaced with more highly alloyed materials such as the AA3000 series types aluminium alloys.
  • AA3102 and AA3003 are examples of higher strength aluminium alloys having good corrosion resistance.
  • Aluminium alloys of the AA3000 series type have found extensive use in the automotive industry due to their good combination of strength, light weight, corrosion resistance and extrudability. These alloys are often made into tubing for use in heat exchanger or air conditioning condenser applications.
  • U.S. Patent no. 5,286,316 discloses an aluminium alloy with both high extrudability and high corrosion resistance.
  • This alloy consists essentially of about 0.1 - 0.5 % by weight of manganese, about 0.05 - 0.12 % by weight of silicon, about 0.10 - 0.20 % by weight of titanium, about 0.15 - 0.25 % by weight of iron, with the balance aluminium and incidental impurities.
  • the alloy preferably is essentially copper free, with copper being limited to not more than 0.01 %.
  • the alloy disclosed in U.S. Patent no. 5,286,316 offers improved corrosion resistance over AA3102, even more corrosion resistance is desirable.
  • a still further object of the present invention is to provide an aluminium alloy which has good both hot- and cold- formability and corrosion resistance.
  • the present invention provides a corrosion resistant aluminium alloy consisting essentially of, in weight percent, 0,05 - 1 ,00 % of iron, 0,05 - 0,60 % of silicon, less than 0,50 % of copper, up to 1 ,20 % of manganese, 0,02 - 0,20 % of zirconium, up to 0,50 % of chromium, 0,02 to 1 ,00 % of zinc, 0,02 - 0,20 % of titanium, 0,02 - 0,20 % of vanadium, up to 2,00 % of magnesium, up to 0,10 % of antimony, up to 0,02 % of incidental impurities and the balance aluminium.
  • iron preferably is between 0,05 - 0,55 %, more preferably, between 0,05 - 0,25 %. Reducing the Fe content improves the corrosion resistance. Silicon is preferably between 0,05 and 0,20 %, more preferably, not more than 0,15 %. Copper is below 0,50 %, as this elements normally negatively influences the extrusion speed and the corrosion resistance. But in some circumstances some copper might be needed to adjust the electro-potential of the allay. Preferablly the Cu-content is below 0,05 % by weight. Zirconium is preferably between 0,02 and 0,18 %.
  • Zn should always be present in at least 0,02 % by weight in order to improve the general level of corrosion resistance and preferably zinc content is between 0,10 and 0,50 %, more preferably between 0,10 and 0,25 %.
  • Ttitanium is preferably between 0,02 and 0,15 %, and vanadium is preferably between 0,02 and 0,12 %.
  • the preferred amount of manganese is highly dependent on the intended use of the article because manganese impacts extrudability, especially with thin sections. For applications with these type of alloys in which the corrosion resistance and excellent extrudability is the primary concern, manganese is preferably present in amounts between 0,05 - 0,30 % by weight. Fe is preferably present in amounts between 0,05 - 0,25 % by weight.
  • the preferred amount of chromium is between 0,02 and 0,25%.
  • the magnesium amount is preferably below 0,03 %.
  • Zn is preferably present in amounts between 0,10 - 0,5 % by weight.
  • chromium is preferably between 0,02 and 0,18 % by weight and magnesium below 0,30 % by weight, for brazeability reasons.
  • the Fe content should be kept low for improved corrosion resistance.
  • chromium is added to further improve corrosion resistance.
  • Zn is added to further improve corrosion resistance.
  • controlled additions of V, Zr and Ti are made to further improve, corrosion resistance.
  • the role of V, Ti and especially Zr becomes important.
  • the amounts added of each of these elements will depend on the functional requirements, however, the amount of zirconium is preferably between 0,10 and 0,18 % by weight.
  • post heat treatment of the cast alloy in that it is heated to a temperature of between 450 and 550°C with a heating rate of less than 150 °C/hour, and maintain the alloy at that temperature for between 2 and 10 hours.
  • the final product may also for certain applications and especially after cold working, require a "back annealing" treatment consisting of heating the work piece to temperatures between 150 and 350 degrees Centigrade and keep at temperature for between 10 and 10000 min.
  • Zr and Ti in solid solution are used separately to improve corrosion resistance in low alloy highly extrudable alloys e.g. for use in extruded tubes for automotive AC systems.
  • the useful maximum additions of Zr and Ti when added separately is less than 0,2% by weight. Above this level primary compounds are formed that reduces the level of these elements in solid solution.
  • the primary compounds from Zr and Ti (AI3Zr, AI3Ti) may initiate pitting corrosion as they are more noble than the Al matrix. Both Zr and Ti will upon solidification go through a peritectic reaction. The product of this reaction is revealed as a highly concentrated region of the elements in the centre of the grain (large positive partition ratio). These regions or zones will upon rolling or extrusion form a lamellae structure parallel to the surface of the work piece and slow down the corrosion in the through thickness direction.
  • V is an element with much the same behaviour and effect as Zr and Ti, but has up to now not been used much in these type of alloys. V will improve the mechanical properties in the same way as Zr and Ti, but do not have the same effect on corrosion unless the Zr-content is higher than the V-content.
  • the transition elements such as Zr, Ti, and V are known to improve formability by increasing the work hardening coefficient ("n").
  • the "n” increases with increased amount of the transition elements almost linearly up to some 0,5%.
  • Zr, Ti and V up to 0,45% of the transition elements may be added without the formation of deleterious primary particles of the type AI3Zr, as opposed to below 0,2% if only one of the elements is added. But it has found otherwise that above a total level of 0,3 % by weight some characteristics are negatively influenced.
  • Zr, Ti and V, and in particular Zr are known to impede the tendency of recrystalization, provided optimum heat treatment before high temperature processing.
  • the ability to retard recrystalization is related to the number and size of small coherent/semi-coherent precipitates that are stable at temperature up to 300- 400 degrees Centigrade for prolonged times.
  • the fine polygenized structure that will result from back annealing at temperatures in the 150 to 350 degrees Centigrade range will have higher mechanical strength than the corresponding recrystalized structure resulting in the absence of such transition elements.
  • the density of these precipitates increases with increased amount of the transition elements, therefore combining the three elements would improve the mechanical property in the temperature range from ambient temperature to approx. 400 degrees Centigrade.
  • Billets with different content of Zr, V and Ti were cast using the laboratory casting equipment at Sunndals ⁇ ra. For each alloy, four billets with a diameter of 95 mm and a length of 1.1 m were produced. At the beginning of the casting the casting speed was 115 mm/min, increasing to 240 mm/min after 15 cm cast billet. The temperature in the launder was set to be 705°C and the temperature was recorded during casting. Grain refiner (Ti 5 B-wire) were added in the furnace before the casting.
  • each billet were cut, producing three samples for extrusion and two samples for spectrographic analysis (first one sample for spectrographic analysis, then two samples for extrusion, then the second sample for spectrographic analysis (i.e. -in the middle of the billet) and finally the third sample for extrusion).
  • Samples from the as-cast material (-middle of the billet) was etched to reveal feathery crystals, in addition samples were prepared to show grain structure and particle structure. Hardness and conductivity measurements were carried out for each alloy on specimens (2 cm x 2 cm x 1 cm) that were grinded to a grit size of 2000.
