Aluminium Polishing and Finishing Processes: The Story of the Soda Can

During your moments of soda drinking, have you ever paused for a little bit and pondered on the can in your hand? If you’re like most people, your answer is probably never, and that is completely understandable. Soda cans have become so ingrained in people’s daily lives that it’s almost trivial for anyone to wonder about them—people all over the world go through about 180 billion aluminium beverage cans in a year, often totally oblivious of the fact that the seemingly meagre cans in their hands are actually marvels of engineering.

Soda cans as we know them today have been around since the ‘60s, when they were being used for frozen juice concentrate. Then, the American company Reynolds Metals Co. saw an opportunity for aluminium through a survey—they found out that people actually preferred aluminium over tin-plated steel. That opened the flood gates for the production of aluminium beverage cans, which still remain widely used today.
