Interesting that the 'donation' of aluminium pots and pans, in the UK at least, was purely a propaganda thing, the 'brain child' of Lord Beaverbrook, designed to involve the population, so they thought they were helping the war effort by providing materials for aircraft.
The local authorities around the country ended up with huge mounds of scrap aluminium, useless for anything except pots and pans, that they didn't know what to do with!
After the war, they were re-cycled - and made into new pots and pans!!
