Question:

why manufacturers phase out tin in favour of aluminum?compare their chemical and phisical properties?

we can refer to aluminium foila as tin foil and foil was made up of elemental tin.

Answer:

Early 20th century, steel was covered with tin to prevent rustingTin has a low melting point, about 450 degrees so was easy to work with given existing technologyTin shacks, Tin pans and Tin cans were all steel covered with tinMost solder, like that used on the ends of steel cans is still tin Tin is dense, heavy, and relatively expensiveTin suffers metal fatigue worse than aluminum, so bend it too many times, it will break before AlTin is easily mixed with copper, lead, silver or zinc to make brass, bronze, and pewter Aluminum is prevalent, cheap, melts at a higher temp, conducts heat and electricity wellI would bet there was at one time actual tin foil, which was replace by aluminum in maybe the 50's or 60's when aluminum was cheap to make.
