Here's why:
* Titanium is expensive: Titanium is a very strong and corrosion-resistant metal, but it's also much more expensive than steel.
* Steel is sufficient: The opening tab on a soda can doesn't need to be as strong or corrosion-resistant as the main body of the can, so steel is a more cost-effective option.
* Aluminum is the primary material: Soda cans are primarily made from aluminum, which is lightweight and recyclable. The opening tab is usually made from a different type of metal, like steel, to provide the necessary strength.
So, while the opening tab might look silvery like titanium, it's actually made of a more affordable and readily available material.
