铝

• Pinyin: lǚ
• Hanzi breakdown: 铝 = 钅(metal radical) + 吕 (phonetic component lǚ)

Meaning

Aluminium (aluminum); chemical element Al, atomic number 13. A lightweight, silvery-white metal and the most abundant metallic element in the Earth's crust.

China is the world's largest aluminium producer and consumer. Key compounds: 铝合金 (aluminium alloy), 铝箔 (aluminium foil), 铝材 (aluminium materials). Widely used in aerospace, construction, packaging, and electronics.

Examples

1. 铝合金因其轻便耐用的特性被广泛应用于航空航天制造领域。 Because aluminum alloy is lightweight and durable, it is widely used in aerospace manufacturing.
2. 这款包装采用铝箔材料，能有效隔绝空气和湿气，延长食品的保质期。 This packaging uses aluminum foil, which effectively blocks air and moisture and extends the food’s shelf life.
3. 铝是地壳中含量最丰富的金属元素，储量约占地壳总重量的百分之八。 Aluminum is the most abundant metallic element in the Earth’s crust, accounting for about 8% of its total weight.
