铝是制造飞机的重要材料,有人称它“有翼的金属”。1852年,人类第一次把铝提炼出来。1854年,法国人开始用化学方法来正式生产铝。但是用这种方法炼铝成本很大,产品比白银还贵,直到1890年为止,三十年间,全世界才生产了200多吨铝。十九世纪八十年代末,用电解法代替化学法炼铝以后,大大地降低了铝的成本,为铝工业的迅速发展创造了有利的条件。近几年来,世界各国铝生产的增长速度,在有色金属中,除了一些稀有金属(如钛、铍、锆)
Aluminum is an important material for the manufacture of aircraft. Some people call it “winged metal.” In 1852, humans first extracted aluminum. In 1854, the French began chemical production of aluminum. However, the cost of smelting aluminum by this method is very high, and the product is more expensive than silver. Until 1890, in the past 30 years, the world had produced more than 200 tons of aluminum. At the end of the 1980s, the use of electrolysis instead of chemical aluminum smelting greatly reduced the cost of aluminum and created favorable conditions for the rapid development of the aluminum industry. In recent years, the growth rate of aluminum production in countries around the world is in non-ferrous metals, except some rare metals (such as titanium, hafnium, and zirconium).
