<Aluminum>
It is called light silver (keigin) because it is light and resembles silver in appearance. It is a silver-white, soft, light metal that is highly malleable and ductile, and can be made into thin foil. Because of its high reflectivity, high-purity aluminum is used in reflective mirrors for optical equipment. It is also used in electrolytic capacitor foils, magnetic disks, laser reflectors, vapor deposition materials for integrated circuits, etc. Because of its light weight, it is used in aircraft, automobiles, ships, and railways, and because it is a good conductor of electricity, it is used in power transmission lines.
