O alumínio é barato ou caro?

The price of aluminum changes depending on market rates, how pure it is, what alloys are mixed in, its shape, how much is being bought, where it’s being sold, and if it’s new or recycled. Aluminum is usually seen as cost-effective because it’s light, resistant to rust, and can be reused, which might save money in the long run even if it costs more at first. The cost can go up and down because of how much is available, how much people want it, and how much it costs to make.
