Why does Coca-Cola have aluminum cans and steel cans?

No, aluminum cans for Coca-Cola or cola drinks are cheap and easy to process. Besides, the steel cans you mentioned are tinplate cans, which have high cost and slow production. Most coke products in China are aluminum cans, which is beneficial to mass production and price competition. The tinned Coca-Cola you mentioned may be imported or imported from other channels. If it is also made in China, please tell me where it is made. I'm also interested. Thank you!
