Alcoa says the need for aluminium is only going to go up.
Aluminum is used in cars, planes, cans and kitchens.
Alcoa chief executive Klaus Kleinfled says demand grew 13% last year and predicts global demand will double until 2020.
He says aluminium is prominent in the fast-changing consumer electronics sector, as the market values the properties of the metal.
Mr Kleinfled says aluminium is recyclable and 75% of all the aluminium used in the world, is still in use.
