Pretty useful to visualize the state of the art in the aluminium production, Index Mundi provides us this chart with the data of the industry of aluminium per country.
Though it just shows information of 2003, it is still useful to see how different countries had lead and continue leading the aluminium production economy.
I would be interesting to compare, for example Mexican foundries profitability with Mexican suppliers of aluminium.
You can visualize directly the information in the Aluminum Production Index Mundi Webpage.
