aluminum alloy

Encyclopedia Article


An alloy is a metal that is made by combining at least two other metals or a metal and a nonmetal element. The characteristics of an alloy are different than the characteristics of the separate elements. Aluminum alloy includes mainly aluminum. By combining aluminum and copper, in the right amounts, results in a lightweight metal that is stronger and lighter than either aluminum or copper were before they were combined. Because they are relatively light, aluminum alloys are commonly found in transportation technologies including aerospace equipment, automobiles, and cycling frames.
