Phrases like 'tin foil' and 'tin cans' give the impression that tin is some cheap and disposable metal but in reality these are simply outdated holdovers from the 1930's and prior. The tin was quietly replaced with aluminum and steel because they were cheaper and more practical but consumers never got the memo so they kept using the antiquated terms.

Tin is actually not all that cheap and is pretty rare in commerce except for solder and pewter; both of which are low melting alloys. However, for all effects and purposes can only be obtained as a commodity from refineries and their distributors (or laboratories) because there's just no remaining use for the metal in pure form.
