Definitions
- the invention relates to an improved aluminium alloy and more particularly to an aluminium alloy which contains controlled amounts of defined compounds and is characterized 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 relatively high strength and low weight.
- aluminium alloys for use in heat exchangers or air conditioning condensers.
- the alloy must have a good strength, a sufficient corrosion resistance and good extrudability.
- a typical alloy used in this application is AA 3102. Typically this alloy contains approximately 0,43% by weight Fe, 0,12% by weight Si and 0,25% by weight Mn.
- W097/46726 there is described an aluminium alloy containing up to 0,03% by weight copper; between 0,05 - 0,12% by weight silicon, between 0,1 and 0,5% by weight manganese, between 0,03 and 0,30 % by weight titanium between 0,06 and 1 ,0% weight zinc, less than 0,01% by weight of magnesium, up to 0,50% by weight iron, less than 0,01 % by weight nickel and up to 0,50% by weight chromium.
- the aluminium alloy according to the present invention includes controlled amounts of iron, silicon, manganese, zirconium, chromium and zinc.
- an aluminium-based alloys consisting about 0,06-0,25 % by weight of iron, 0,05-0,15 % by weight of silicon up to 0,70 % by weight of copper, up to 0,10% by weight of manganese, 0,02 to 0,20% by weight zirconium, up to 0,18% by weight chromium, up to 0,70 % by weight of zinc, 0,005 to 0,02% by weight titanium, for grain refining puroses, up to 0,02 % by weight of incidental impurities and the balance aluminium, said aluminium-based alloy exhibiting high corrosion resistance, good extrudability and acceptable tensile strength.
- the iron content of the alloy according to the invention is between about 0,06-0,15 % by weight. In this way the corrosion resistance and the extrudability is optimal, as both characteristics are substantially reduced with high iron content.
- the zirconium content is preferably between 0,10-0,18 % by weight. In this range the extrudability of the alloy is practically not influenced by any change in the amount of zirconium.
- the chromium content is between 0,10-0,18 % by weight.
- An increase in chromium content results in an increased resistance against corrosion, within this range the extrudability is slightly reduced but still within an acceptable range.
- Zinc will in even small consentration, negatively affect the anodizing properties of AA 6000 alloys. In view of this polluting effect of zinc, the level of Zn should be kept low to make the alloy more recycleable and save costs in the cast house. Otherwise, zinc has a positive effect on the corrosion resistance up to at least 0,7 % by weight, but for the reason given above the amount of zinc is preferable between 0,10 - 0,18 % by weight.
- copper may be present to up to 0,50 % by weight, it is preferred to have the copper content below 0,01 % by weight in order to have the best possible extrudability. In some circumstances it might be necessary to add copper to the alloy to control the corrosion potential, making the product less electo negative, to avoid galvanic corrosion attack of the product. It has been found that copper increases the corrosion potential with some 100mV for each % of copper added, but at the same time decreases the extrudability substantially.
- the invention also relates to an aluminium product obtained by means of extrusion and based upon an aluminium alloy according to the invention.
- the alloy will be homogenized by means of an heat treatment at elevated temperatures, e.g. 550-610°C during 3-10 hours. It has been found that by such a heat treatment the extrudability was slightly improved, but the corrosion resistance was negatively influenced.
- the aluminium product is characterized in that the only heat treatment of the aluminium alloy after casting is the preheating immediately before extrusion.
- Such preheating takes place at lower temperatures than the homogenization step and only takes a few minutes, so that the characteristics of the alloy with respect to extrudability and corrosion resistance are hardly effected.
- alloys according to the invention have been prepared, which alloys are listed below in table 1 the alloys A - E.
- table 1 the composition of these alloys has been indicated in % by weight, taking into account that each of these alloys may contain up to 0,02 % by weight of incidental impurities.
- table 1 is also shown the composition of the traditional 3102-alloy. All these alloys have been prepared in the traditional way . The extrusion of the billet after preparation of the alloy was preceded by a preheating to temperatures between 460-490°C. Table 1 : Chemical composition of the different alloys
- test sample was an extruded tube with a wall thickness of 0,4mm.
- test as described are in general use with the automotive industry, where an acceptable performance is qualified as being above 20 days.
- the testing of mechanical properties was carried out on a budget Universal Testing Instrument (Module 167500) and in accordance with the Euronorm standard. In the testing the E-module was fixed to 70000N/mm 2 during the entire testing. The speed of the test was constant and 10 N/mm 2 per second until Rp0,2 was reached, whilst the testing speed from Rp0,2 until fracture was 40% Lo/min, Lo being the initial gauge length.
- the extrudability is affected by small additions of the different alloying elements. By introducing Cr and Zr it is seen that the die force and the maximum force increases (i.e. the extrudability is reduced). Zinc, on the other hand, does not affect the extrudability in any significant way which as such is well known.
- the mechanical properties in terms of ultimate tensile strength and yield strength are seen to be significantly improved when Cr is added. In that case the new alloys match the 3102 alloy properties.
- the corrosion test have been performed on samples taken at different location of the coil. About 10 samples were taken from the very start of the coil (from the front of the billet), 10 samples from the middle part of the coil (middle part of the billet) and 10 samples from the end of the coil (end of the billet). Each sample was about 50 cm long. The results were very consistent which means that there is no effects on the corrosion resistance related to extrusion speed and material flow during the exterusion of one billet, for the extrusion parameters used.
- Fig. 1 shows the influence of the Fe-content on the characteristics of the alloy according to the invention.
- Fig. 2 shows the influence of the Mn-content on the characteristics of the alloy according to the invention.
- Fig. 3 shows the influence of the Zr-content on the characteristics of the alloy according to the invention.
- Fig. 4 shows the influence of the Cr-content on the characteristics of the alloy according to the invention.
- Fig. 5 shows the influence of the Zn-content on the characteristics of the alloy according to the invention.
- Fig. 6 shows the influence of the Cn-content on the characteristics of the alloy according to the invention.
- the x-axis represents the content of the alloying agent expressed in % by weight
- the y-axis is a relative representation of the different properties
- the square dots being used to represent the ultimate tensile strength in MPa
- the black triangular dots being used to represent the entrudability expressed in ktons and using the die force as representative measurement
- the white triangular dots being used to represent the SWAAT-test results expressed in days.
- the corrosion resistance is reduced in a significant way with higher Fe-contents (keeping Si-content at the same level of 0,08 % by weight). This effect especially occurs at Fe-contents in the range of 0,2 - 0,3 % by weight.
- the extrudability is significantly reduced with higher Fe-contents. It should be noted that a reduction of 2-3% of the extrudability (expressed as 2-3% increase of the break through pressure) is an unacceptable increase for an extrusion plant. Otherwise an increase of the Fe-content results in an increase of the tensile strength.
- Fig.6 there is shown a diagram showing the influence of the Cu-content on the extrudability and on the corrosion potential.
- the amount of Cu in % by weight On the X-axis is shown the amount of Cu in % by weight, whereas the left Y-axis is the extrusion force expressed in kN and the right Y-axis is the corrosion potential expressed in mV according to ASTM G69.
- the upper line in the graph is the evolution of the corrosion potential, whereas the lower line is the evolution of the extrusion force.
- the extruded product such as a heat exchanger tube
- another product such as a header with a clad containing no Zinc
- Cu additions modify the corrosion potential of the extruded product in such a way that the tube becomes more noble (less negative) than the header material. This will curb any attacks of the tube due to galvanic corrosion.
