In a Game of Physical Properties, Bronze Bars Win Gold Every Time

"If physical properties had their way, bronze would be the winner’s medal. Gold is too soft to stand alone and must form an alloy with other, stronger metals for durability. The same can be said for copper, which results in bronze, but it’s more abundant. Metal distributors such as Rotax Metals can manufacture bronze bars for an affordable cost. If needed, both metals can be recycled. Copper recycling has been in practice as early as the age of bronze artillery, melting the cannons after a war to be remade into useful items. As only the physical form of copper and copper alloys change, not the chemical structure, remade bronze sheet metal still possesses the same properties as scrap copper."
