One of the advantages of aluminum alloy compared with other metals: lightness

Aluminum alloy has a relatively low density and is the 1 lightweight material. Compared with other metal materials such as steel or copper, aluminum alloy has a smaller proportion, which makes products made of aluminum alloy lighter and easier to carry and transport. For example, aircraft parts commonly used in the aerospace industry and car bodies commonly used in the vehicle manufacturing industry often use aluminum alloys to improve fuel efficiency and performance.
