Aluminum cans for beer and other drinks have been popular all over the world since the 60s of the last century. In the USA, almost 100% of beer is sold in aluminum cans, in Europe - about 50%. Aluminum cans are consumed in huge quantities, mainly in two types of containers: 0.33 and 0.50 liters. High volume production justifies high speed, high precision production lines. In addition, these basic sizes of aluminum cans have the same diameter, use the same lids, and differ only in height.
A huge advantage of aluminum beer cans over the main competitor - glass - the ability to completely recycle aluminum cans after using them into new ones beer cans.
How much does a beer can weigh
- The weight of an aluminum can is decreasing from year to year: in 25 years it has become 30 percent lighter.
- A modern, empty 0.5L beer can - body, lid and opening mechanism - weighs about 15.5g
- To collect one kilogram of aluminum scrap from beer cans, you need about 65 of them. For recycling of scrap aluminum cans see.
Design
Aluminum beer cans (and for carbonated drinks too) must withstand an internal overpressure of up to 6 atmospheres. Therefore, the design of the can includes a thick domed bottom and rather thin walls, which, however, with the help of internal pressure, provide the can with sufficient structural strength. A general view of a typical beer can and the purpose of its various elements is shown in Figure 1.
Figure 1 - Details of the structure of an aluminum can and their functions
Height and diameter of the beer can
Domestic normative document for the design of an aluminum can - GOST R 51756-2001 “Deep-drawn aluminum cans with easily opened lids”. It is, of course, consistent with similar international guidelines. According to it, the main parameters and dimensions of beer aluminum cans are as follows (with an accuracy of 1 mm).
Beer can height:
- Bank with a capacity of 0.33 l - 115 mm
- Bank with a capacity of 0.05 l - 168 mm
Beer can diameter:
- The bottom of the can - 66 mm
- The lid of the can is 59 mm.
Beer can wall thickness
The body of an aluminum can is made by drawing in two passes from a flat round billet, the so-called "cup". Then the walls of this cup are thinned during their successive rolling to a thickness of only one third of the original (Figure 2). The bottom of the can is specially profiled not only to withstand high internal pressure, but also for good alignment with the lid of the downstream aluminum can - for ease of packaging. The wall of the can is rolled out to a thickness of 0.110 mm over almost the entire height. Currently, the minimum wall thickness is reported to be as high as 0.08 mm.
Figure 2 - The wall thickness of the can has different thicknesses.
In the upper part of the body of the can, the wall is thicker and the thickness of the beer can in this place is 0.16 mm. This is necessary both for the convenience of forming a narrowed "neck", and for creating a strong connection with the lid. The aluminum can lids are supplied separately and are fitted to the body using the well-known “double lock” seam immediately after the can is filled with beer or other beverage (Figure 3).
Figure 3 - The design of the connection of the can lid with its body:
double lock seam
Beer can lid
The popularity of aluminum beer cans began to explode in 1964, when the “easy-open” lid was invented. This lid was opened with bare hands by simply turning a special “lug” (Figure 4). The eyelet is installed on the cover using a so-called integral rivet (Figure 5). It is called integral because it is formed directly from the metal of the cover.
Figure 4 - The lid opens easily and remains on the can
Figure 5 - Technology of forming an integral rivet on a can lid
Beer can opening mechanism
The task of the ear and the petal (it is also called the "tongue") is to achieve the cotton of the emitted carbon dioxide with an effort on the ear of about 3 kilograms and completely pushing the petal (tongue) inside the can with an effort of up to 7 kilograms, and the petal must remain hanging inside the can.
This is achieved by making special notches along the perimeter of the petal of such a depth that only 0.085 mm of metal remains near the rivet and 0.110 mm on the opposite side (Figure 6). At the same time, the material on the notches is strong enough not to collapse during technological process or when unloading in a store.
Inside the petal, you can see another, inner row of notches. They are not so deep and serve, it is said, for the directional flow of metal on the main cuts and to prevent the main cuts from breaking during their formation.
Figure 6 - Sophisticated notches provide
reliable opening of the can in two stages:
first release the gas, then pushing the petal inside the can
Materials (edit)
Requirements for materials
The main requirement for the materials of beer cans is their ability to form with large plastic deformations. Aluminum alloys are ideal in this sense. In addition, the ability to predictably burst along the notches is important for the lids of beer cans. Aluminum does this much better than steel. Another positive point is that both the body and the cover are aluminum, which minimizes any potential galvanic effects that could lead to accelerated corrosion.
Body material
Details of beer cans are made of aluminum-manganese and aluminum-magnesium alloys (table). For the body of the can, tapes with a thickness of 0.30 mm made of aluminum alloy 3004 or its modification - aluminum alloy 3104 - in the H19 state are used.
Cover and ear materials
For the covers, a varnished tape made of aluminum alloy 5182 in the Н48 condition with a thickness of 0.26 mm is used, and for the manufacture of "ears" - keys for easy opening - a strip of aluminum alloy 5042 in the Н18 condition with a thickness of 0.45 mm.

Technology
Production cycle of aluminum cans
The picture below shows the production cycle for aluminum cans for beer and soft drinks.
Figure 7 - Typical production cycle for aluminum beer cans
Aluminum sheet in rolls
Plants for the production of aluminum beer cans consume a large amount of aluminum sheet, which comes in large rolls. The body and lid of the can are made of aluminum sheets - from various aluminum alloys. Each roll weighs about 11 tons and when it is unwound, the sheet travels a distance of 9-13 kilometers.
The aluminum coils enter the aluminum can plant and are loaded into an “uncoiler”. This is the machine that unwinds the aluminum sheet at the beginning of the can production line. Here, a special lubricant is applied to the aluminum sheet. This lubricant helps the aluminum sheet to go through all shaping operations more “smoothly”, without damage.
Can body manufacturing
A typical sequence of technological operations for the manufacture of a can body is shown in Figure 7. The first operation in the manufacture of cans is cutting round billets, for example, with a diameter of 140 mm. Naturally, this felling produces waste: these losses are about 12-14%. They are immediately sent to be smelted to make a new sheet and new beer cans.
From the original round billet by deep drawing (stamping) an intermediate billet is obtained - a shallow "cup" (Figures 8 and 9). An almost finished can body is obtained from this “cup” by rolling, and the bottom dome is also formed (Figures 8, 10, 11). Then this semi-finished jar is washed, drawings are applied to it and varnished, and only after that its mechanical molding is completed - the formation of the neck and flanging (Figure 8).

Figure 9 - Deep drawing - "cup" forming 
Figure 10 - Rolling out the can wall 
Figure 11- Forming the bottom
Making a beer can lid
Aluminum sheet is fed in rolls weighing up to 8 tons. Up to 2.5 million caps are produced from each roll. The aluminum sheet, which is pre-coated, is fed into a special press, on which an almost finished cover is stamped. Then the complex edge of the lid is formed, which will then ensure its reliable connection with the body of the can.
Figure 12 - Not yet fully finished lid
Making a beer can ear
The technology for making the eyelet - the key-opener - includes about 13 operations (Figure 13) before it can be installed on the lid.

Scrap aluminum beer cans
One beer can with a capacity of 0.5 liters weighs about 15.5 g. For one kilogram of aluminum scrap from 0.5 liter beer cans, it is necessary to collect about 65 pieces of them.
