Definitions
- the invention is related to a new aluminum alloy.
- the invention further relates to a method of producing highly shaped aluminum products, such as bottles or cans, using the aluminum alloy.
- the manufacturing process typically involves first producing a cylinder using a drawing and wall ironing (DWI) process.
- DWI drawing and wall ironing
- the resulting cylinder is then formed into a bottle shape using, for example, a sequence of full-body necking steps, blow molding, or other mechanical shaping, or a combination of these processes.
- the demands on any alloy used in such a process or combination of processes are complex.
- a final requirement is the ability to form the bottles at a high speed.
- a high throughput e.g., 1000 bottles per minute
- the shaping of the bottle must be completed in a very short time.
- methods are needed for making preforms from the alloy at high speeds and levels of runability, such as that demonstrated by the current can body alloy AA3104.
- AA3104 contains a high volume fraction of coarse intermetallic particles formed during casting and modified during homogenization and rolling. These particles play a major role in die cleaning during the DWI process, helping to remove any aluminum or aluminum oxide build-up on the dies, which improves both the metal surface appearance and also the runability of the sheet.
- novel alloys that display high strain rate formability at elevated temperatures.
- the alloys can be used for producing highly shaped aluminum products, including bottles and cans.
- the aluminum alloy described herein comprises about 0.15-0.50 % Si, 0.35-0.65 % Fe, 0.05-0.30 % Cu, 0.60-1.10 % Mn, 0.80-1.30 % Mg, 0.000-0.0080 % Cr, 0.000-0.500 % Zn, 0.000-0.080 % Ti, up to 0.15 % of impurities, with the remainder as Al (all in weight percentage (wt. %)).
- products e.g., bottles and cans
- an aluminum alloy as described herein.
- the methods include direct chill (DC) casting of an aluminum alloy as described herein to form a metal product, homogenizing the metal product, hot rolling the metal product to produce a metal sheet, cold rolling the metal sheet (e.g., with a 60 % to 90 % thickness rejection), optionally recrystallization annealing the rolled sheet, cold rolling the annealed sheet, and stabilization annealing the rolled sheet.
- DC direct chill
- Products e.g., bottles or cans obtained according to the methods are also provided herein.
- Figure 1 is a scanning transmission electron microscopy (STEM) micrograph of an aluminum alloy according to an embodiment of the invention showing a substructure with average geometrically necessary boundary (GNB) spacing larger than 300 nm.

- the method of making an aluminum alloy as described herein comprises direct chill casting an aluminum ingot; homogenizing the ingot; hot rolling the ingot to form a hot rolled product; cold rolling the hot rolled product in a first cold rolling step to form a first cold rolled product, wherein the first cold rolling step produces an about 60-90 % thickness reduction in the hot rolled product; cold rolling the first cold rolled product in a second cold rolling step, wherein the second cold rolling step produces an about 15-30 % thickness reduction in the product; and stabilization annealing of the second cold rolled product, wherein the stabilization annealing is at a metal temperature from about 100-300 °C for about 0.5-4 hrs.
- the alloys described herein can be cast into ingots using a direct chill (DC) process.
- the DC casting process is performed according to standards commonly used in the aluminum industry as known to one of skill in the art.
- the casting process can include a continuous casting process.
- the continuous casting may include, but are not limited to, twin roll casters, twin belt casters, and block casters.
- the alloys are not processed using continuous casting methods.
- the cast ingot can then be subjected to further processing steps to form a metal sheet.
- the further processing steps include subjecting a metal ingot to a homogenization cycle, a hot rolling step, a cold rolling step, an optional recrystallization annealing step, a second cold rolling step, and a stabilization annealing step.
- the homogenization step can involve a one-step homogenization or a two-step homogenization. In some embodiments of the homogenization step, a one-step
- homogenization is performed in which an ingot prepared from the alloy compositions described herein is heated to attain a peak metal temperature (PMT). The ingot is then allowed to soak (i.e., held at the indicated temperature) for a period of time during the first stage.
- PMT peak metal temperature
- a two-step homogenization is performed where an ingot prepared from an alloy composition described herein is heated to attain a first temperature and then allowed to soak for a period of time In the second stage, the ingot can be cooled to a temperature lower than the temperature used in the first stage and then allowed to soak for a period of time during the second stage.
- the ingots can be hot rolled to an 5 mm thick gauge or less.
- the ingots can be hot rolled to a 4 mm thick gauge or less, 3 mm thick gauge or less, 2 mm thick gauge or less, or 1 mm thick gauge or less.
- the hot rolling speed and temperature can be controlled such that full recrystallization of the hot rolled materials is achieved during coiling at the exit of the tandem mill.
- a first cold rolling step produces a reduction in thickness of from about 60-90 % (e.g. about 50-80 %, about 60-70 %, about 50-90 %, or about 60-80 %).
- the first cold rolling step produces a reduction in thickness of about 65 %, about 70 %, about 75 %, about 80 %, about 85 %, or about 90 %.
- a second cold rolling step produces a further reduction in thickness of from about 15-30 % (e.g., from about 20-25%, about 15-25%, about 15-20%, about 20-30%, or about 25-30 %).
- the second cold rolling step produces a further reduction in thickness of about 15 %, 20 %, 25 %, or 30 %.
- recrystallization annealing is at a metal temperature from about 300-450 °C. In one embodiment, the recrystallization is for about 1-2 hrs.
- the recrystallization annealing step can include heating the alloy from room temperature to a temperature from about 290 °C to about 500 °C (e.g., from about 300 °C to about 450 °C, from about 325 °C to about 425 °C, from about 300 °C to about 400 °C, from about 400 °C to about 500 °C, from about 330 °C to about 470 °C, from about 375 °C to about 450 °C, or from about 450 °C to about 500 °C).
- a temperature from about 290 °C to about 500 °C e.g., from about 300 °C to about 450 °C, from about 325 °C to about 425 °C, from about 300 °C to about 400 °C, from about 400 °
- an annealing step is stabilization annealing (e.g., after the final cold rolling).
- the stabilization annealing is at a metal temperature from about 100-300 °C for about 0.5-4 hrs. In one embodiment, the stabilization annealing is at a metal temperature from about 120-250 °C for about 1-2 hrs.
- the stabilization annealing step can include heating the alloy from room temperature to a temperature from about 100°C to about 300 °C (e.g., from about 120 °C to about 250 °C, from about 125 °C to about 200 °C, from about 200 °C to about 300 °C, from about 150 °C to about 275 °C, from about 225 °C to about 300 °C, or from about 100 °C to about 175 °C).
- a temperature from about 100°C to about 300 °C (e.g., from about 120 °C to about 250 °C, from about 125 °C to about 200 °C, from about 200 °C to about 300 °C, from about 150 °C to about 275 °C, from about 225 °C to about 300 °C, or from about 100 °C to about 175 °C).
- the shaped aluminum bottle of the present invention may be used for beverages including but not limited to soft drinks, water, beer, energy drinks and other beverages.
