Soda cans are typically made from an aluminum alloy known as 3004 or 3104. These alloys are specifically designed for beverage can applications due to their excellent formability, high strength, and good corrosion resistance.
The 3004 and 3104 alloys contain a small percentage of magnesium, which enhances their strength and formability. They also have a protective coating on the inside to prevent the soda from reacting with the aluminum.
These aluminum grades are chosen for soda cans because they provide a lightweight and durable packaging solution. The high strength-to-weight ratio of aluminum allows for efficient transportation and storage of beverages. Additionally, aluminum is infinitely recyclable, making it an environmentally friendly choice for packaging materials.
