美国铝业分司采用已获得专利的一项提纯新工艺开始工业规模地生产集成电路广泛使用的五个“9”以上的超高纯铝,成为美国第一家超纯铝生产和供应厂商。该公司所生产的超纯铝,其成分不同于欧洲和远东一些铝生产厂商供应的铝,其铀和钍的含量极抵。采用结晶提纯的新技术将铀、钍和其它有害杂质去除到集成电路制造厂家可以接受的水平。美国铝业 Alcoa Division of the United States to adopt a patented a new purification process began the industrial scale production of integrated circuits widely used five “9” above the ultra-high purity aluminum, the United States became the first ultra-pure aluminum production and suppliers. The company produces ultra-pure aluminum, a component that is different from the aluminum supplied by some aluminum producers in Europe and the Far East, with extremely high levels of uranium and thorium. New technologies utilizing crystallization purification remove uranium, thorium and other harmful impurities to levels acceptable to integrated circuit manufacturers. American Aluminum
