What Materials Are Used for Making Tin Cans?

Tin materials are rare metals. Meaning, making tin cans using pure tin is very expensive and difficult.

Thus, tin cans that are produced from the modern production process usually have no tin in them, opposite to its name.

Most modern tin cans are made from treated materials such as aluminum, tin-plated steel, and more.

What are the Differences Between Tin and Aluminum Cans?

Both cans are used for packaging food and beverages. If you are stuck between the two, here are some of their differences to help you choose for your applications.

• Aluminum cans are lightweight while tin cans are heavier.
• Tin cans are more durable than aluminum cans.
• Tin cans have higher corrosion-resistance properties than aluminum cans.
• Aluminum cans have a more recycling efficiency than tin cans.

What are the Common Shapes of a Tin Can?
