What do beer cans make of?

The birthday of the beer can be considered January 24, 1935.It was then that the first time they spilled beer in such a container. The cost of this package is much less than glass. In addition, banks made bright, inflicted information about the company. First, for the use of three pieces of iron, and for the opening required a special key. The modern ringlet appeared only in 1963.And now many people ask themselves: what do beer cans make of? We will try to eliminate this gap in overall development.

What does the bank consist of?

Most often, the volume of such a vessel is 0.5 and 0.33 liters. Produce them on high-speed, high-precision production lines.

Important! The main advantage of this material is that it can be completely recycled.

The beer can, like any other carbonated beverage, must cope with internal excess pressure, which can reach six atmospheres. That is why their design provides for a thick dome-shaped bottom and sufficiently thin walls. But these walls make the construction quite solid. What do beer cans make of? From aluminum, and in this way:

• A flat circular blank is pulled out until a "cup" is obtained.
• Then the thinning of its walls is performed.
• The bottom is profiled in a special way so that it can cope with high internal pressure. In addition, it should have a good alignment with the lid - so it will be more convenient to perform packaging.
• The can walls are adjusted to a thickness of 0.08 mm almost everywhere. However, on top they are thicker - 0.16 mm.

Important! So it is necessary to form a narrowed neck, and also to create a strong connection with the lid.

• The cover is also made of aluminum. Its delivery is carried out separately.
• A joint "double lock" is used to connect the cover and the housing.
• It is performed after a beer or other drink is poured into the jar.

Features of the

cover In order for everything to work properly, an aluminum alloy with a slightly different composition is used for the lid than for the case. The can has a concave bottom, so the design copes with the pressure of the drink. In addition, the risk that the bank will be damaged during transportation and storage is reduced.

So, what are the technological features of manufacture:

• The lid is made flat, as its main characteristics are hardness and strength. Aluminum alloy in a larger quantity contains magnesium and in smaller - manganese than in the case with the body.
• The thickness of the lid is much larger than that of the entire can.
• The middle part of this part is slightly convex. It is pressed out so that the rivet turns out.
• A separate metal part is a key ring, it is applied from above and fixed with a rivet.
• Then the grooves are made. They are necessary so that when the key is opened, the lid partially bends inward and the opening is correct.

And again - why aluminum?

The main requirement for the material is the possibility of large plastic deformations during molding. Aluminum - that's what made a beer can, it's just perfect. In addition, the lids of beer cans should bend over the notches, which is not achieved in steel.

Important! One of the positive aspects of the fact that all the parts of the can are made from one material is that galvanic effects, leading to accelerated formation of rust, can not occur.

What is the use of cans for packaging?

• Thanks to such packaging, unlike glass, beer is not exposed to sunlight and oxygen. In bottles, oxygen is provided by the lining in the lid. Very few people are interested in drinking sour beer.
• Due to the penetration of sunlight, the drink has an unpleasant taste and odor. After opening the bottle, it is enough to smell the smell. If it smells of burnt rubber - the beer is spoiled.
• It is believed that the best beer - draft. And it, by the way, is poured into kegs from metal, and the bank - just their miniature copy.

Important! There are a few other things:

• It takes much less time to cool the can of beer in the refrigerator.
• The weight of the can is much smaller.
• It's not so easy for a bank to break if compared to a glass bottle.

• Every time a new, clean jar is used in production. But in the case of bottles, reuse is common.

We are so used to beer in banks that sometimes we do not think about what this container actually made of. Now we have opened the veil of secrecy for you, and you can flash knowledge in the company.
