What is a tuna can made of?

Here's a breakdown:

* Tinplate is a thin sheet of steel coated with a layer of tin.

* Tin is a soft, silvery-white metal that resists corrosion.

* Steel provides the strength and durability to hold the contents.

The tin coating protects the steel from rusting, which is essential for storing food safely.

Some tuna cans may be made from aluminum or steel with a protective coating other than tin. However, tinplate remains the most common material for tuna cans.
