About

铝 is a modern phono-semantic compound coined for the Western scientific term aluminum. It combines the metal radical 钅 (simplified from 金) with the phonetic component 吕 (lǚ), which approximates the first syllable of "aluminum" (Latin aluminium). The traditional character is 鋁, with the unsimplified radical 金 and phonetic 呂. The character exclusively denotes the chemical element aluminum, a lightweight, silvery-white metal used in industrial manufacturing, construction, and everyday packaging.
