铝的重要价值铝是一种银白色的轻金属。它宛如一位淑女,着一身银白色的素裹;体质轻盈,在常温时比重只有2.7;具青春活力,对热和电的反应十分敏感,有良好的传导性能;品格温顺,易于加工,并容易和其他金属熔合成合金;素质非常好,耐酸碱、抗腐蚀,制成合金后具有良好的结构性能和很高的强度。一百多年前,铝象黄金一样贵重。法国统帅拿破仑三世曾经用铝制做了一个头盔,以显示他的豪华和尊贵。一八二五年,丹麦人厄尔斯泰首先用钾汞齐还原无水氯化铝,制得了不太纯的金属铝。到一八九六年,美国人霍尔和法国人埃鲁特同时发明了电解制铝
The important value of aluminum is a silvery white light metal. It is like a lady with a silvery white wrap; light weight, only 2.7 weight at room temperature; youthful vigor, very sensitive to heat and electricity, good conductive properties; docile, easy to process, and It is easy to alloy with other metals; it is very good in quality, acid and alkali resistant, corrosion resistant, and has good structural properties and high strength after alloying. More than 100 years ago, aluminum was as precious as gold. French commander Napoleon III used aluminum as a helmet to show his luxury and dignity. In 1825, Danske Erstein first reduced anhydrous aluminum chloride with potassium amalgam to produce a less pure metal aluminum. In 1896, American Hall and Frenchman Erut invented electrolytic aluminum production.
