The physical state of aluminum is dependant on the temperature. This metal exists as a solid at temperatures below its melting point of 1220.58 degrees Fahrenheit, at which it becomes a liquid. At temperatures above 4566 Degrees Fahrenheit, aluminum becomes a gas.
Until 1886, aluminum was rare and more valuable than gold. Charles Martin Hall's discovery of an electrolytic reduction process made aluminum less valuable and more common in use. Its special properties allow manufacturers to find new applications regularly. Recycling aluminum products requires far less energy than refining more aluminum from ore. In the United States, approximately half of the 1 billion aluminum cans shipped annually are recycled.
