About

The character 铝 is a modern phono-semantic compound formed to translate Western scientific terminology into Chinese. It uses the metal radical 钅 on the left to classify the substance as a metallic element, while the right component 吕 serves as a phonetic marker, approximating the first syllable of "aluminum" or "aluminium". Its traditional form, 鋁, pairs the unsimplified metal radical 金 with the phonetic element 呂. The character refers exclusively to the chemical element aluminum, the lightweight, silvery-white metal widely used in industry, construction, and packaging.
