In food cans it must be steel (Ferrum), not tin (Stannum), of course.  They
look like covered with some other layer (to stop corrosion while they are in
use). My understanding is that this layer can be destroyed in fire,  so they
will eventually last shorter.  Anyway, I couldn't come with another
solution.
