Description

5xxx aluminum sheet for can manufacturing

The present invention relates to 5xxx series alloy aluminum sheets and methods of making the same, particularly useful in the can manufacturing industry.

As a known efficient and environmentally friendly solution for beverage packaging, aluminum beverage cans are very popular.

To minimize _CO2 emissions, can manufacturers are working to reduce the weight of the can body and can ends and increase the recycled content of the solution. It is worth emphasizing that using 1 tonne of scrap instead of 1 tonne of primary metal reduces _CO2 emissions by 10 tonnes.

For the can end, also called the lid, can manufacturers used an optimized design to gradually reduce the can end diameter from 68.3 mm to 54 mm and then to 50.8 mm. The combination of the smaller diameter and the new can end design enabled a thickness reduction from 223 μm to about 203 μm and an associated significant weight reduction.

However, can edge lightweighting has been experiencing a “plateau” over the past few years, and it is now increasingly difficult to reduce thickness below 200 μm.

The alloy used to manufacture the can ends is typically alloy AA5182. Because of its high mechanical properties, AA5182 requires a high level of purity (e.g. Fe, Si) to achieve the required molding properties. Such a high level of purity in AA5182 limits its recycled content and means that the precision of the AA5182 can ends relies on primary aluminum. The more primary aluminum is used, the more important the CO ₂ emissions are.

Additionally, since there is a greater amount of metal in the can body than in the can end, it is desirable to have the possibility of recycling the can end and the can body together. For this reason, specific can end and can body alloys have been developed.

In the can manufacturing industry, there is a need for improved aluminum sheet products for manufacturing can ends with the right balance between different criteria (strength, formability and high recyclability).

The first object of the present invention is to provide an aluminum sheet made of 5xxx series aluminum sheets comprising the following composition in weight percent (wt%):

Mg: 2.50 - 4.00;

Mn: 0.70 - 1.20;

- casting an ingot with the composition according to the invention;

- Preheating the ingot to a temperature usually between 440°C and 550°C;

- hot rough rolling the ingot on a reversible rolling mill with a rough hot rolling inlet temperature exceeding 440°C;

- finish hot rolling the ingot with a hot rolling exit temperature of at least 300°C;

- cold rolling to obtain cold rolled sheets; and

- Optionally coating the cold rolled sheet.

Another object of the invention is to provide a can end obtained from the sheet according to the invention.

Another object of the present invention is to provide a beverage can obtained from the can end according to the present invention and the can body made of AA3xxx alloy.

All aluminum alloys referred to hereinafter, unless otherwise noted, are designated using the rules and nomenclature established by the Aluminum Association in its regularly published Registration Record series.

The metallurgical tempers referred to below are specified using the European standard EN-515 (April 2017).

All alloy compositions are given in weight percent (wt%). The expression “7.9 Mn” means the manganese content expressed in weight percent multiplied by 7.9.

Tensile testing was performed according to ISO/DIS 6892-1 (July 2014).

The present inventors have discovered an improved 5xxx aluminum alloy sheet with a good balance between different criteria (strength, formability and high recyclability).

The Mg content is 2.50% to 4.00% by weight, preferably 2.50% to 3.85% by weight, more preferably 3.10% to 3.85% by weight, even more preferably 3.10% to 3.65% by weight.

Mg is the main alloying element in the alloy and contributes to improving strength. If the Mg content is less than 2.50% by weight, strength improvement may be insufficient. On the other hand, content exceeding 4.00% by weight may result in lower moldability. Minimum Mg contents of 3.00%, 3.05%, 3.10%, 3.15%, 3.20%, 3.25%, 3.30%, 3.35% or 3.40% by weight may be advantageous. A maximum Mg content of 3.85%, 3.80%, 3.75%, 3.70%, 3.65% or 3.60% by weight may be advantageous.

Additionally, Mn is an element effective in improving strength, refining grains, and stabilizing the structure. The Mn content is 0.70% to 1.20% by weight, preferably 0.80% to 1.15% by weight, more preferably 0.90% to 1.10% by weight, even more preferably 0.92% to 0.98% by weight.

When the Mn content is less than 0.70% by weight, the above-mentioned effect is insufficient. On the other hand, an Mn content exceeding 1.20% by weight not only causes saturation of the above-mentioned effect, but also may cause the generation of a plurality of intermetallic compounds that may adversely affect formability. Moreover, the Mn content of the present invention ensures that, in one embodiment, the addition of recycled scrap, more specifically UBC (Use Beverage Can) scrap, is maximized during the casting step. Minimum Mn contents of 0.76%, 0.78%, 0.80%, 0.85%, 0.90%, 0.91%, 0.92% or 0.93% may be advantageous. A maximum Mn content of 1.15%, 1.10%, 1.05%, 1.00%, 0.98% or 0.96% by weight may be advantageous.

Control of Fe and Si is important to achieve the desired properties of the sheets of the invention, especially a balance between formability and recyclability. The Fe content is 0.25% to 0.55% by weight, preferably 0.30% to 0.40% by weight.

Fe contents below 0.25% by weight may not produce a sufficient effect, while Fe contents above 0.55% by weight may result in molding difficulties associated with the formation of a large Al ₆ MnFe primary phase. A minimum Fe content of 0.28%, 0.30% or 0.31% by weight may be advantageous. A maximum Fe content of 0.45%, 0.40% or 0.38% by weight may be advantageous.

The Mn and Mg contents are preferably related to the Fe content. Preferably, for an Fe content of at least 0.50% by weight, the sum of Mg + 7.9 Mn is at most 11.4% by weight, preferably at most 10.7% by weight, more preferably at most 10.1% by weight, and at least 0.44% by weight (and For an Fe content of less than 0.50% by weight), the sum of Mg + 7.9 Mn is at most 12.1% by weight, preferably at most 11.4% by weight, more preferably at most 10.8% by weight, and at least 0.40% by weight (and 0.44% by weight) For an Fe content of less than), the sum of Mg + 7.9 Mn is at most 12.5% by weight, preferably at most 11.8% by weight, more preferably at most 11.2% by weight, and at least 0.35% by weight (and less than 0.40% by weight). For Fe content, the sum of Mg + 7.9 Mn is at most 12.8% by weight, preferably at most 12.1% by weight, more preferably at most 11.5% by weight, with an Fe content of at least 0.30% by weight (and less than 0.35% by weight). In this case, the sum of Mg + 7.9 Mn is at most 13.1% by weight, preferably at most 12.4% by weight, more preferably at most 11.8% by weight, for an Fe content of at least 0.25% by weight (and less than 0.30% by weight) by Mg The sum of + 7.9 Mn is at most 13.5% by weight, preferably at most 12.8% by weight, more preferably at most 12.2% by weight. In a preferred embodiment, the Fe content is 0.30% to 0.40% by weight, and the sum of Mg + 7.9% by weight is 8.0% to 12.5% by weight, preferably 9.4% to 11.8% by weight, more preferably 10.2% by weight. to 11.2% by weight. The claimed Fe, Mn and Mg contents ensure maximum addition of recycled scrap, more specifically UBC scrap, especially during the casting step.

The Si content is 0.20% to 0.50% by weight, preferably 0.22% to 0.35% by weight, more preferably 0.23% to 0.30% by weight. Excessive addition of Si may produce more Mg ₂ Si phases, which may adversely affect formability. A minimum Si content of 0.21%, 0.22%, 0.23% or 0.24% by weight may be advantageous. A maximum Si content of 0.40%, 0.35%, 0.30% or 0.28% by weight may be advantageous.

The Cu content is 0.10% to 0.25% by weight, preferably 0.10% to 0.20% by weight, more preferably 0.12% to 0.20% by weight. Because Cu in solid solution may be advantageous for strength and/or formability, a minimum Cu content of 0.11 wt%, 0.12 wt%, 0.13 wt% or 0.14 wt% may be advantageous. Since the formation of Cu-containing phases can adversely affect formability, a maximum Cu content of 0.25%, 0.20% or 0.18% by weight may be advantageous. In one embodiment, the Cu content is 0.14% to 0.18% by weight.

The Cr content is 0.10% by weight or less, preferably 0.05% by weight or less. In one embodiment, some Cr may be added in an amount of 0.01% to 0.05% by weight, preferably 0.01% to 0.03% by weight, for strength improvement, grain refinement, and structure stabilization.

Zn may be added in an amount of 0.25% by weight or less, preferably 0.20% by weight or less or 0.15% by weight or less, without departing from the advantages of the present invention. In one embodiment, Zn is one of the unavoidable impurities.

A grain refiner comprising Ti is added, usually with a total Ti content of 0.10% by weight or less, preferably 0.005% to 0.05% by weight, more preferably 0.01% to 0.03% by weight. In one embodiment, the Ti content is 150 ppm to 250 ppm.

The balance is aluminum and unavoidable impurities up to 0.05% by weight each and up to 0.15% by weight in total.

According to the invention, the ingot is produced by casting, usually by Direct-Chill casting or continuous casting, using the 5xxx series aluminum alloy of the invention. Preferably, the casting step includes melting recycled scrap into liquid metal.

As used herein, the term recycled scrap (e.g., recycled stock) refers to recycled metal comprising primarily aluminum, preferably at least 60%, 70%, 80% or 90% aluminum. It can refer to a set. Recycled scrap can be sourced from a metal manufacturing facility (e.g., a metal foundry), a metal processing facility (e.g., a manufacturing facility that uses metal products to create consumer products), or a post-consumer source (e.g., may include recycled materials from any suitable source, such as a local recycling facility. Certain aspects of the present disclosure may be particularly suitable for recycled scrap from sources other than metal fabrication facilities, as such recycled scrap is likely to contain mixtures of alloys, or other impurities or elements (e.g., paints or coatings, etc.). This is because it is mixed with. Recycled scrap includes recycled sheet aluminum products (e.g., aluminum pots and pans, automotive interior and exterior products), recycled cast aluminum products (e.g., aluminum grills and wheel rims), UBC scrap (e.g., beverage cans), aluminum wire, and extruded materials. and other aluminum materials.

Preferably, the recycled scrap metal includes used beverage can (UBC) scrap, which is metal collected from used beverage cans and similar products that can be recycled for use in other metal products. Aluminum UBC scrap is often a mixture of various aluminum alloys (e.g., from different alloys used in can bodies and can ends) and often contains rainwater, beverage residues, organics (e.g., paints and laminate films), and other materials. may contain foreign substances. UBC scrap may be shredding and subjected to decoating or delacquering before being melted for use as liquid metal stock in casting the new metal products of the present invention. Due to impurities and unbalanced alloying elements present in liquid UBC metal, it may be necessary to treat the liquid UBC metal to remove unwanted elements prior to casting, or to combine the liquid UBC metal with a sufficient amount of fresh primary aluminum. . Similarly, recycled scrap from other sources may have relatively high amounts of impurities and/or unbalanced alloying elements.

The recycled scrap content of the product according to the invention is described herein. For example, the alloy according to the present invention may have about 50% by weight, about 60% by weight, about 70% by weight, about 80% by weight, about 85% by weight, about 90% by weight, about 91% by weight, about 92% by weight. , suitable cast products from modified liquid metal containing greater than about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, or about 99% recycled scrap by weight. This allows it to be manufactured. In other words, the cast articles described herein may have about 50% by weight, about 40% by weight, about 30% by weight, about 20% by weight, about 15% by weight, about 10% by weight, about 9% by weight, or about 8% by weight. %, about 7%, about 6%, about 5%, about 4%, about 3%, about 2%, or less than about 1% by weight primary aluminum and an optional hardener (e.g., Al+ It may include a master alloy containing Cu, Al+Si, Al+Mn, Al+Fe, etc., or a pure metal such as Cu, Mg, Zn, etc.). Certain aspects of the present disclosure relate to metal products manufactured using modified liquid metal, most of which is recycled scrap. Preferably, the recycled scrap includes recycled aluminum scrap such as UBC scrap. For example, UBC scrap generally consists of metal from various alloys, such as metal from the can body (e.g., 3104, 3004, or other 3xxx aluminum alloys) and can ends (e.g., 5182 or other 5xxx aluminum alloys). Contains a mixture. Due to the content of Mg and Mn, the composition of the alloy of the present invention is particularly suitable for recycling UBC scrap. Preferably, the recycled scrap melted in the method of the present invention has about 50% by weight, about 60% by weight, about 70% by weight, about 80% by weight, about 90% by weight, about 91% by weight, about 92% by weight, and greater than about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, or about 99% UBC scrap by weight. Adding primary aluminum reduces the amount of recycled content and increases costs and greenhouse gas emissions because primary aluminum costs more and produces more greenhouse gases than recycled scrap. Therefore, a compromise is often made between processing recycled scrap and adding primary aluminum. Using the inventive alloys described herein, recycled scrap can be used with little or no refining and with little or no addition of primary aluminum and optional hardeners.

The ingot thickness is preferably at least 250 mm, or at least 350 mm, preferably a very thick ingot with a thickness of at least 400 mm, or even at least 500 mm or 600 mm to improve the productivity of the process. Preferably, the ingot is 1000 to 2000 mm wide and 2000 to 8000 mm long. Preferably the ingot is scalped.

The ingot is then preheated to a temperature of usually 440°C to 550°C and hot rolled to obtain a sheet with a thickness of usually 2 to 12 mm. Preferably, the sheet is hot rolled in two successive stages, for example the sheet is hot rolled to a thickness of typically 12 to 40 mm by a first hot rolling stage on a reversible rolling mill, also known as a roughing mill, followed by a finishing mill. It is typically rolled to a thickness of 2 to 12 mm by a second hot rolling step on a tandem mill, also known as a finishing mill. A tandem rolling mill is a rolling mill in which a number of cages, usually two, three, four or five, supporting the mill rolls operate continuously (in “tandem” fashion). According to the invention, hot rough rolling on a reversible rolling mill is carried out with a hot rough rolling inlet temperature of more than 440°C, preferably more than 460°C. The first step on a reversible mill can be carried out on one or even on two reversible mills arranged in series.

In the second hot rolling step, the final temperature, which is the hot rolling exit temperature, is preferably at least such that the hot rolled sheet obtained after hot finish rolling has a volume fraction of recrystallized grains of at least 50%, preferably at least 80%. It should be 300°C, preferably at least 330°C.

To further reduce the thickness of the aluminum sheet, cold rolling is realized immediately after the hot rolling step. By the method of the present invention, annealing after hot rolling or during cold rolling is optional since such steps are not considered essential to obtain sufficient strength, formability, surface quality and corrosion resistance. Preferably, no annealing is performed after hot rolling or during cold rolling. Sheets obtained immediately after cold rolling are referred to as cold rolled sheets. The cold rolled sheet thickness is usually 0.15 to 0.30 mm, preferably 0.18 to 0.23 mm.

In one embodiment, the cross-sectional reduction of cold rolling is at least 80%, or at least 85%.

Preferably, the cold rolled sheet is coated. In one coating process, the cold rolled sheet is cleaned and chemically treated, optionally dried in an oven, and optionally primed, coated and thermally (oven) cured to form a coated sheet. In another coating process, the cold rolled sheet is cleaned, chemically treated, and coated with a suitable (e.g., food grade) electron beam (“EB”) and/or ultraviolet (“UV”) curable coating composition to form a coated sheet. Coated and EB or UV cured.

Preferably, the coating is a BPA-Free or BPA-NI (Bisphenol-A Free or Bisphenol-A Non-Intent) coating or laminate.

Preferably, after simulating baking the coating at 205° C. for 20 minutes, the product of the invention has a tensile yield strength (TYS) in the transverse direction (LT) of 320 MPa to 380 MPa, preferably 320 MPa. to 360 MPa.

Formability is the ability of a sheet to be formed under a specific shape. Formability is particularly related to tensile yield strength (TYS or Rp0.2): as TYS increases formability generally decreases. According to a preferred embodiment, the TYS of the sheet according to the invention is heat treated in the H48 temper or at 205° C. for 20 minutes to simulate baking of the coating and to impart mechanical properties similar to those in the H48 temper, after which the TYS has a temperature of not more than 380 MPa. , preferably 360 MPa or less. According to another preferred embodiment, the TYS of the sheet according to the invention is at least 320 MPa after simulating baking of the coating in H48 temper or by heat treatment at 205° C. for 20 minutes. This minimum TYS allows to achieve sufficient strength and resist internal pressure.

Preferably, the products of the invention are in H4X metallurgical temper state as defined by European standards EN 515 (April 2017) and EN 541 (May 2007).

According to those standards, H4X metallurgical tempers represent strain-hardened, lacquered or painted products. Therefore, H4X is a temper of the material obtained after work hardening and coating, during which a certain level of recovery may occur. The preferred temper is the H48 temper, which is generally assigned the hardest H4X temper produced. The mechanical properties of H48 can be obtained after simulation of baking the coating from cold rolled sheets of H18 or H19 temper at 205°C for 20 minutes.

In particular, the H48 metallurgical temper ensures the shaping of metals for producing can ends for beverage cans. Preferably, the 5xxx series aluminum sheets according to the invention are coated, preferably in H48 temper.

The present invention also relates to a can end obtained from the sheet according to the invention, and to a beverage can obtainable from the can end obtained according to the invention and the can body made of AA3xxx alloy.

The use of 5xxx series aluminum sheets for manufacturing can ends according to the invention is advantageous. In particular, AA3xxx alloys, preferably AA3002, AA3102, AA3003, AA3103, AA3103A, AA3103B, AA3203, AA3403, AA3004, AA3004A, AA3104, AA3204, AA3304, AA3005, AA3005A, AA3105, AA3105A, AA3105B, AA3007, AA3107, AA3207, AA3207A, AA3307, AA3009, AA3010, AA3110, AA3011, AA3012, AA3012A, AA3013, AA3014, AA3015, AA3016, AA3017, AA3019, AA3020, AA3021, AA3025, AA3026, AA3030, AA3130 and AA3 An alloy selected from 065, most preferably AA3004 The use of can ends according to the invention in combination with a can body made of an alloy selected from AA3004A and AA3104 is advantageous because these beverage cans are easy to recycle.
