Definitions
- the invention relates to an aluminium alloy which can be used for heat exchangers.
- the aluminium alloy according to the invention is provided as fin stock material for heat exchanger devices.
- the invention relates a brazed assembly comprising at least one component of the aluminium alloy according to this invention.
- aluminium alloys are the alloys of choice for heat exchanger applications. These alloys are selected for their desirable combination of strength, low weight, good thermal and electrical conductivity, brazeability, corrosion resistance, and formability.
- An aluminium alloy heat exchangers can be fabricated by stacking aluminium alloy clad sheets (brazing sheet), which have been formed to a desired configuration, so as to form fluid passages (tubes) and securing corrugated aluminium alloy fins between fluid passages by brazing.
- the bonding between the alloy clad sheets or the tube material and fins is achieved by melting the brazing filler metal of the core plates and/or fin material.
- a brazing method typically vacuum brazing or flux brazing is being applied.
- some fin materials may be used which are electrochemically anodic (less noble) relative to the fluid passage material by the sacrificial anode effect of these fin materials.
- the 3009 alloy has the following composition, in weight percent: Si 1.0 - 1.8 Fe max. 0.7
- the disclosed alloy may replace the known AA3003 alloy, and may be used for brazing applications.
- EP-A-0637481 discloses an aluminium alloy brazing sheet having a three-layer structure clad one side of the core material with a brazing material and clad of the other side of the core material with a sacrificial material.
- the defined core material has a very wide compositional window, in weight percent- Si 0.6 - 2.5 Cu 0.5 - 2.5 Mn up to 2.0 at least one kind selected from the group consisting of:- Mg 0.03 - 0.5 Cr 0.03 - 0.3 Zr 0.03 - 0.3 Ti 0.03 - 0.3 Ni 0.03 - 1.5 balance aluminium and impurities.
- This document further discloses an aluminium alloy brazing sheet having a three-layer structure cladded on both sides of the core material with a brazing material and whereby the core material has a very wide compositional window, in weight percent:- Si 0.03 - 2.5
- Mn 0.6 - 2.0 at least one kind selected from the group consisting of:- Zn 0.05- 5.0 In 0.002 - 0.3
- aluminium alloys which may be used for application in heat exchangers, which alloys have improved post- brazed strength in combination with a good corrosion resistance. Further, there is a demand from the side of the manufacturers of such aluminium alloys, for alloys having a tolerance for impurity elements from a recycling point of view without compromising to the required properties of such an aluminium alloy.
- the invention provides an aluminium alloy having the composition, in weight percent:
- This aluminium alloy has a good corrosion resistance, which includes the sacrificial anode effect where required, in combination with good mechanical properties in the post-brazing state and is capable of providing an increase in post-braze 0.2% yield strength (PS) of at least 15% over conventional finstock alloys, such as AA3003 in the same temper.
- the aluminium alloy in accordance with the invention is capable of achieving a post-braze 0.2% yield strength (PS) of at least 60 MPa, and in the best examples of at least 65 MPa and even as a high as 70 MPa or more.
- this aluminium alloy can be used for tube plate, side supports and header tanks in heat exchanger units, and may have other uses, it is primarily intended as a finstock alloy for heat exchangers.
- the corrosion demand for finstock is such that if the heat exchanger unit is attacked by corrosion, the fin material is preferentially attacked and not the tube material.
- the alloy according to this invention has this sacrificial anode effect.
- the alloy can be stronger, so the finstock can be thinner and lighter than conventional finstock alloys, such as AA3003 alloys.
- the alloy of the invention used as finstock material may be used in combination with a cladding of a brazing alloy, e.g. an Al-Si alloy known in the art or other similar Al-Si systems alloys, such as Al-Si-Mg alloy, Al-Si-Mg-Bi alloy, Al-Si-Bi alloy or the like.
- finstock alloys offer a balance of properties, i.e. strength, formability, brazeability and corrosion potential.
- a key feature of the novel alloy of this invention is the relatively high Si content as compared to AA3003 alloys, in combination with a medium Mn content. Consequently this increases the post-braze strength, by more than 15% relative to conventional finstock alloys.
- the alloy exhibits amongst others excellent brazeability properties.
- All composition percentages are by weight.
- Si is an important alloying element in the alloy according to this invention. The addition of Si results in an increased solution hardening of the alloy.
- the sum of Si+Mn is in the range of 1.6-2.3, and more preferably in the range of 1.75-2.1, and allows for a good compromise in desired properties of the alloy such as post-braze strength and sag-resistance, while the alloy can be manufactured without great difficulties from scrap material.
- Mn is also an important alloying element in the alloy according to this invention.
- a more preferred upper limit for the Mn content is 1.1%
- the Mn should be in the range of 0.8 to 1.0%.
- a very high Mn content might lead to the detrimental formation of large Fe-Mn intermetallics.
- the Mn level should not exceed 1.2%. Above 1.2% Mn the casting of an ingot becomes more difficult.
- Mg increases the strength of the alloy significantly, but has a detrimental influence on controlled atmosphere brazeability because it tends to interact with the flux applied. For this reason the Mg content is restricted to a maximum of 0.35%, and a more preferred range for the Mg level is 0.2 to 0.35% as a compromise in post-braze strength and brazeability.
- Fe is present in all known aluminium alloys. With a too high Fe content among other things the formability of the material decreases and also the corrosion performance is decreasing.
- the admissible Fe content is 0.8% maximum, and preferably 0.5% maximum. Such relatively high Fe contents may be tolerated by limiting the Mn content.
- a suitable Fe content is in the range of 0.20 to 0.45%, and allows for a good compromise in desired properties of the alloy such as post-braze strength and sag-resistance, while the alloy can be manufactured without great difficulties from scrap material.
- the fin material should be more electronegative as the tube material. Since different types of tube material can and will be used in heat exchangers, the Zn content can be used to tune the corrosion potential of the alloy of this invention to fit to the tube material. The Zn content should be at a level below 3.0% to avoid a too rapid corrosion attack of the fin material.
- Zn may be tolerated up to 3.0%, and preferably up to 2.0%, and more preferably up to 1.5%, and most preferably up to 1.0%, this achieves an advantage in the tolerance of this alloy for impurity elements, and allows this alloy to be composed from large amounts of scrap material, such as discarded heat exchangers, but not limited to this example.
- a suitable lower limit for the Zn-level is 0.2%.
- Ni may be present in the alloy according to the invention in a range up to 1.5% in order to further increase the post-braze strength without resulting in a significant loss in thermal conductivity.
- a preferred range for Ni as an alloying element is 0.3 to 1.2%, and more preferably 0.5 to 0.75%. This enables the alloy of the invention to reach a better and desirable balance between post-braze strength, thermal conductivity and corrosion resistance.
- Cu is preferably included as a strengthening component. Cu is believed not to reduce corrosion resistance in a way that has previously been reported. Since Cu may be tolerated up to 0.5%, this achieves an advantages in the tolerance of this alloy for impurity elements, and allows this alloy to be composed from large amounts of scrap material, such as discarded heat exchangers, but not limited to this example.
- a suitable maximum for the Cu content is up to 0.5%, and preferably up to 0.4%.
- a more preferred range for the Cu-level is 0.2 to 0.4% as a compromise in achieving post-braze strength, corrosion resistance and brazeability.
- Ti may be present up to 0.20% to act as a grain refining additive during the casting of an ingot of the alloy of the invention. Additional Ti may be added, for example due to their presence in scrap material, in order to increase the strength of the alloy by solubility hardening.
- the total amount of Ti present in the alloy should not exceed 0.20%, but preferably is less than 0.15%.
- the element Indium in a range of up to 0.20% may be added to the alloy of the invention in order to reach a more electro-negative corrosion potential.
- In it has been found in accordance with the invention that in this aluminium alloy In is much more effective in reducing the corrosion potential of the alloy as compared to zinc additions. Typically 0.1% In is as effective as 2.5% Zn.
- a more preferred range for In is 0.01 to 0.10%.
- Zr in a range of up to 0.25% may be added to the alloy of this invention in order to further improve the strength of the alloy in the post-braze condition. Further, this element may be tolerated as an impurity element without detoriating the desired properties of the alloy.
- a more suitable Zr addition is in the range of 0.05 to 0.20, and more preferably in the range of 0.05 to 0.15%.
- Cr in a range of up to 0.25% may be added to the alloy of this invention in order to further improve the strength of the alloy in the post-braze condition.
- Sn and V may be tolerated in the alloy according to the invention in a range up to 0.25%, preferably up to 0.15%, and more preferably up to
- the balance is made by aluminium and unavoidable impurities, typically each up to 0.05% maximum, and in total 0.15% maximum.
- a brazed assembly typically a heat exchanger, comprising the alloy of the invention as fin stock material.
- the fins may act as a sacrificial anode.
- the aluminium alloy according to the invention may also be clad on one or both of its surfaces.
- the purpose of such a cladding is essentially to provide the brazing material for the fillets, and is used for example in the case of unclad tubes like for condensers made from extruded tubes or for serpentine type evaporators.
- each clad layer thickness is in the range of 2 to 15% of the total thickness of the clad product.
- the composition of the clad layer is typically in the range of 5 to 15% Si, optionally up to 2.0% Mg, optionally up to 3.0% Zn, and optionally up to 0.2% Bi.
- the aluminium alloy in accordance with this invention can be manufactured using various standard industrial scale DC casting and continuous aluminium casting methods, followed by hot and/or cold rolling.
- the chemical compositions are listed in Table 1, where Alloys 1 to 4 are alloys according to the invention with Ti at grain refiner level, Alloy 5 and 6 are alloys according to the invention with a somewhat increased Mg- and Ti-level, Alloy 6 further has an increased Zn-level.
- Alloy 6 further has an increased Zn-level.
- the Ni-, In-, and V-levels are at impurity level.
- Alloy 7 is the example in the H 14 temper known from the international patent application WO-97/18946 for comparison reasons, and further an Alloy 8 has been used which is the known AA3003 alloy commercially used as finstock material.
- the four cast ingots were preheated and hot rolled to a thickness of 5.7 mm.
- the sheets were then cold rolled to 0.15 mm and annealed at 360-400°C for 2 hours before cold rolling to a final gauge of 0.10 mm. This is the H14 temper.
- the cold rolled sheets had the following mechanical properties before and after being subjected to a simulated brazing cycle (approx. 5 min at 590°C and air cool), see Table 2.
- the mechanical properties are valid for non-clad material.
- the alloy of the invention may be provided with a thin cladding, resulting in a small decrease of the mechanical properties (both in the pre- and post-braze conditions) of a few MPa, typically about 2 to 10 MPa. From these results it can be seen that the aluminium alloy of the invention has a significant improvement in mechanical properties over the conventional used AA3003 alloy in the same temper, and offer the opportunity for down gauging of units prior to the brazing cycle and having a reduced rate of corrosion attack on the fin.
- Table 1 Chemical composition, in wt.%, of the aluminium alloys tested, the balance is aluminium and impurities.
