Tin foil was once common wrapping material for drugs and foods, such as chocolate. Replaced by aluminum foil, tin foil is still used as a generic term for silver metal that comes in thin sheets. Tin cans, tin ceiling panels, and corrugated building sheathing are more often made of steel or aluminum with a coating of tin to inhibit rust.
Tin is alloyed with copper to produce bronze, and with copper, antimony and lead to produce pewter. If someone called you a “tinnie”, you might be one who enjoys a can of beer.
