pu1. Wouldn't iron be more expensive because aluminum is more common than iron? Nickel-silver pots are cheap, but stainless steel is expensive

pu2. Aluminum is more expensive. It is true that aluminum is more common, but the process of refining aluminum is more complicated than iron, so the unit price of aluminum becomes more expensive

pu3=뿌2. The casting process of extracting iron from iron ore is very simple, but the process of extracting aluminum metal from the bauxite, which is a gemstone of aluminum, is very complicated and aluminum becomes more expensive
