Definitions
- the invention relates to a brazed heat exchanger comprising various components and at least one component being made from the rolled 6xxx-series aluminium alloy product according to this invention.
- the invention relates further to the use of the rolled aluminium alloy in a heat exchanger.
- Heat exchangers and other similar equipment such as condensers, evaporators and the like for use in car coolers, air conditioning systems, industrial cooling systems, etc. usually comprise a number of heat exchange tubes arranged in parallel between two headers, each tube joined at either end to one of the headers. Corrugated fins are disposed in an airflow clearance between adjacent heat exchange tubes and are brazed to the respective tubes. These various components are commonly joined to each other done by brazing.
- a brazing filler metal or brazing alloy, or a composition producing a brazing alloy upon heating is applied to at least one portion of the substrate to be brazed. After the substrate parts are assembled, they are heated until the brazing metal or brazing alloy melts. The melting point of the brazing material is lower than the melting point of the aluminium substrate or aluminium core sheet.
- Brazing sheet products find wide applications in heat exchangers and other similar equipment.
- Conventional brazing products have a core of rolled sheet, typically an aluminium alloy of the 3xxx-series, having on at least one surface of the core sheet an aluminium clad layer (also known as an aluminium cladding layer).
- the aluminium clad layer is commonly made of a 4xxx-series alloy comprising silicon in an amount in the range of 4% to 20%, and preferably in the range of about 6% to 14%.
- the aluminium clad layer may be coupled or bonded to the core alloy in various ways known in the art, for example by means of roll bonding, cladding spray-forming or semi-continuous or continuous casting processes.
- These aluminium clad layers have a liquidus temperature typically in the range of about 540°C to 615°C.
- brazing sheet products Although commercially sold brazing sheet products have predominantly a core alloy based on a 3xxx-series aluminium alloys, there are commercially available brazing sheet products having a heat-treatable 6xxx-series aluminium alloy as core alloy. These 6xxx-series alloys can be used also base plate of a heat exchanger or for manufacturing headers or side plates of a heat exchanger. Within the 6xxx- series alloys the alloys AA6101 , AA6151 , AA6951 , AA6060, AA6061 , and AA6063 can be found. A list of the key alloying elements of these alloys is given in Table 1 .
- aluminium alloy designations and temper designations refer to the Aluminium Association designations in Aluminium Standards and Data and the Registration Records, as published by the Aluminium Association in 2015 and are well known to the person skilled in the art.
- the temper designations are laid down in European standard EN515.
- the term "about" when used to describe a compositional range or amount of an alloying addition means that the actual amount of the alloying addition may vary from the nominal intended amount due to factors such as standard processing variations as understood by those skilled in the art.
- up to and “up to about”, as employed herein, explicitly includes, but is not limited to, the possibility of zero weight-percent of the particular alloying component to which it refers.
- up to 0.3% Ti may include an alloy having no Ti.
- a brazed heat exchanger incorporating at least one component made from a rolled 6xxx-series aluminium alloy having a composition, and wherein the rolled 6xxx-series aluminium alloy has a composition of: Si 0.2% to 1 .3%, Mg 0.3% to 1 .3%, Cu up to 0.80%, Fe 0.05% to 1 .0%, Mn 0.05% to 0.70%, optionally one or two elements selected from the group of 0.05-0.35% Zr and 0.04- 0.35% Cr, Zn up to 0.25%, Ti up to 0.25%, balance unavoidable impurities and aluminium, and wherein the Fe/Mn ratio is ⁇ 1 .90.
- the rolled 6xxx-series aluminium alloy forms one of the components of a heat exchanger device and the rolled aluminium alloy used provides a good balance in post-braze mechanical properties and enhanced corrosion resistance, in particular after long term exposure at elevated temperatures, for example for 1 ,000 hours at 150°C, reflecting long term use of such a heat exchanger device. This would also allow some down-gauging of the heat exchanger component made from this 6xxx-series alloy.
- the purposive combined addition of Mg and Si strengthens the aluminium alloy due to precipitation hardening of elemental Si and Mg2Si formed under the co- presence of Mg.
- the Si content should be at least 0.20%, and preferably at least 0.25%.
- a preferred upper-limit for the Si content is about 0.8%, and more preferably about 0.60%, and more preferably about 0.55%.
- the presence of Si enhances also the formability.
- the Mg content should be at least 0.3%, and preferably at least about 0.35%, and more preferably at least 0.40% to provide sufficient strength to the rolled product.
- a preferred upper-limit for the Mg content is about 0.9%, and more preferably about 0.8%.
- Fe is not a desired component of the aluminium alloy, but its presence is normally unavoidable.
- the Fe-content should not exceed 1 .0%, and a preferred upper- limit is about 0.8%, and more preferably about 0.50%.
- a preferred range is 0.05% to about 0.40%, and more preferably from about 0.10% to about 0.40%, because alloys containing less Fe are more expensive.
- the presence of substantial amounts of Fe in the aluminium alloy has an adverse effect on the post-braze corrosion resistance.
- the purposive effect of Mn to the aluminium alloy may significantly improve the post- braze corrosion resistance, for example the resistance to intergranular corrosion (IGC), in particular after long term exposure at elevated temperature and it increases the post-braze strength via solid solution hardening.
- IRC intergranular corrosion
- 6xxx-series aluminium alloy according to the prior art and used in heat exchangers may have a presence of some Mn, it is referred to only by an upper-limit and thereby clearly suggesting that it is a tolerable impurity and the skilled person is expected to work at the lower-end of any disclosed Mn-range.
- At least 0.05% Mn must be present.
- at least 0.08% Mn is present, and more preferably >0.10% Mn.
- a preferred upper-limit is about 0.50%, and more preferably about 0.40%.
- the Fe/Mn ratio is being controlled and the Fe/Mn-ratio should not exceed 1 .90, and preferably does not exceed 1 .80, and more preferably does not exceed 1 .75.
- a preferred lower-limit for the Fe-Mn ratio is about 0.7.
- Cu may increase the post-braze strength of the aluminium alloy, but its presence should not exceed 0.80%. It is preferred that the Cu-level does not exceed about 0.4%. Cu levels above about 0.4% may rise to a reduced post-braze corrosion resistance of products incorporating the aluminium alloy according to the invention.
- Ti may be present up to about 0.25% to act as a grain refining additive during the casting of an ingot of the aluminium 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 core alloy by solubility hardening.
- the total amount of Ti present in the alloy should preferably not exceed about 0.20%, but preferably is less than about 0.12%. A preferred lower limit for the Ti addition is about 0.01 %.
- Ti can be added as a sole element or with either boron or carbon as known in the art serving as a casting aid, for grain size control.
- the Zn content in the aluminium alloy is present as a tolerable impurity element of less than about 0.25%, and preferably should be present at the lower-end of this range, e.g. less than about 0.15%, and more preferably less than about 0.10%, to maintain corrosion resistance at desired levels.
- To the aluminium alloy one or two dispersoid forming elements selected from the group consisting of about 0.05% to about 0.35% Zr and about 0.04% to about 0.35% Cr can be added to further improve the strength of the aluminium alloy product in the post-braze condition.
- a more preferred Zr level is in the range of about 0.05% to about 0.20%, and more preferably in a range of about 0.06% to about 0.15%.
- a more preferred Cr level is in the range of about 0.05% to about 0.20%, and more preferably in a range of about 0.06% to about 0.25%.
- the total combined amount of all the dispersoid forming alloying elements Zr and Cr does not exceed about 0.35% to avoid the formation of coarse constituent particles in particular when combined with a relative high Fe content in combination with the purposive addition of Mn.
- Coarse constituent particles may have an adverse effect on formability and they may hinder further down-gauging of the product form and they can have an adverse effect on the corrosion resistance.
- the aluminium alloy it has no purposive addition of vanadium such that, if present, it is at a level of less than about 0.05%, and more preferably less than about 0.03%, such that the aluminium alloy is substantially free from V.
- substantially free or “essentially free” is meant that no purposeful addition was made to the chemical composition but that due to impurities and/or leaking from contact with manufacturing equipment, trace quantities of V may nevertheless find their way into the alloy product. For example, less than about 0.02% is an example of a trace quantity.
- the aluminium alloy may have 0% V.
- the aluminium alloy may contain normal and inevitable impurities, typically each ⁇ 0.05% and the total ⁇ 0.2%, and the balance is made by aluminium.
- the 6xxx-series core alloy has a composition consisting of, in wt.%: Si 0.2% to 1 .3%, Mg 0.3% to 1 .3%, Cu up to 0.80%, Fe 0.05% to 1 .0%, Mn 0.05% to 0.70%, optionally one or two elements selected from the group 0.05%-0.35% Zr and 0.04%-0.35% Cr, Zn up to 0.25%, Ti up to 0.25%, balance unavoidable impurities and aluminium, and wherein the Fe/Mn ratio is ⁇ 1 .90, and with preferred narrower alloy compositions are herein described.

- a brazing sheet material would be used for manufacturing a brazed tube as one of the components of the heat exchanger.
- the 6xxx-series core alloy and the clad brazing material are separated by an interliner or an interlayer, such that the core is bonded to an interliner, and the interliner is, in turn, bonded to the 4xxx-series alloy.
- This structure minimizes localized corrosion, pro- motes good brazeability, reduces liquid film migration, and, by suitable selection of the interliner alloy, enhances corrosion resistance, such that the interliner alloy sac- rificially protects the underlying core alloy.
- An example of a suitable interliner would be an 1xxx- or 3xxx-series alloy, or a 1xxx- or 3xxx-series alloy with a purposive addition of Zn below about 3%, or a purposive addition of In below about 1 %.
