Which element is commonly used to make beverage cans?

• A. Sodium
• B. Fluorine
• C. Aluminum
• D. Neon

Answer: (C)

Aluminum is used because it has a combination of properties that fit packaging needs: it’s light, so cans are easy to carry; it’s malleable, allowing thin-walled, strong cans to be formed by shaping processes; and it forms a protective oxide layer that resists corrosion, helping keep beverages safe. Interior coatings can further prevent any reaction with drinks, while aluminum’s barrier qualities and compatibility with recycling make it economical and environmentally friendly. In contrast, sodium would react with moisture, fluorine is highly reactive and would corrode most materials, and neon is a gas, so it can’t be made into a solid container. That’s why aluminum is the common choice for beverage cans.
