Which Grade of Aluminum is Used for Soda Cans?
We all enjoy our favorite carbonated beverages in a can, but have you ever wondered what grade of aluminum is used for soda cans? Let's find out!
Aluminum for Cans.
Aluminum is an excellent material for soda cans because it is strong and lightweight. Moreover, it is highly resistant to corrosion and does not react with acidic and carbonated beverages. Aluminum cans are also 100% recyclable and have a long shelf life, making them the best choice for the beverage industry.
Grade 3004 H19.
The grade of aluminum used for soda cans is 3004 H19. This aluminum alloy contains approximately 1% manganese, which makes it highly suitable for forming operations such as deep drawing and shaping. H19 refers to the strain-hardened state of the metal, which gives it its strength.
Formation of Soda Cans.
The process of forming soda cans involves several stages. Firstly, aluminum sheets are rolled and cut into circles that are slightly larger than the size of the can. These circles are then cleaned and coated with a layer of organic material to help protect the contents of the can from reacting with the metal.
Next, the circles are formed into cups by a process called deep drawing. A punch is used to press the circles into a die, which forms the cup shape. The cups are then trimmed and cleaned before they are coated with a second layer of organic material to protect the aluminum from abrasion during transport and storage.
After coating, the cans are dried, printed, and decorated with the brand name and logo. A top lid is placed over the opening of the can and sealed in place using a crimping process.
Soda Can Recycling.
One of the great advantages of aluminum cans is that they are easy to recycle. In fact, aluminum cans are one of the most recycled items in the world. Every part of the can, including the paint and the organic coating, can be recycled, and the recycling process uses only 5% of the energy required to create new aluminum.
Final thoughts.
Aluminum cans are the preferred choice for carbonated beverages because of their many benefits. The grade of aluminum used in soda cans is 3004 H19, which is a strain-hardened alloy that is highly formable. The process of creating soda cans involves several stages, including deep drawing, coating, printing, and crimping.
