Aluminium obtained from recycling was considered inferior to primary aluminium because of poorer chemistry control as well as poor removal of dross and slags. Recycling grew overall but depended largely on the output of primary production: for instance... Aluminium is a good electrical conductor and is often used in electrical transmission lines. It is cheaper than copper and weight for weight is almost twice as good a conductor. When evaporated in a vacuum, aluminium forms a highly reflective coating for both light and heat. When mercury is added to aluminum, it forms an amalgam (a mercury alloy). Aluminum is normally protected by a thick oxide layer, but the formation of the ama... But recycling aluminium uses a fraction of the energy. "Beverage cans get recycled within 60 days, so a can of soda is back on the shelves 60 days later," says Nick Madden, who is responsible for buying raw metal for Novelis, the world's biggest manufacturer of rolled aluminium sheets.
