- A silver-colored, nonmagnetic, lightweight metal used extensively in the construction industry. It is used in sheets, extrusions, foils, and castings. Sheets are often anodized for greater corrosion resistance and surface hardness. Because of its light weight and good electrical conductivity, aluminum is used extensively for electrical cables. Aluminum is usually used in alloy form for greater strength.
- A lightweight metallic chemical element whose atomic number is 13. It is the most abundant metal in the earth's crust, and the third most abundant element on the planet. It has about 15 known isotopes of which one is stable, is ductile, malleable, and a good electrical conductor. Its many applications in electronics include uses in semiconductor doping, in manufacturing of chips and hard disks, and as a chassis for metal components. Its chemical symbol is Al. Also spelled aluminium.
