1983年春季在巴黎航空展览会上,为航空工业提供货源的两个最大的铝合金生产企业——英国阿尔康铝业公司和美国阿尔考铝业公司,宣布研制了一种新的、革命性的材料:铝-锂合金。这两个公司各自独立地研制出了这种材料。他们认为,这种新材料是从1943年发明Al-Zn系高强铝合金(7075铝合金)以来在铝合金领域里最重要的发展。他们还认为,Al-Li合金是铝工业对于先进碳纤维增强塑料威胁着铝工业作为航空工业主要材料供货者地位的最好回答。他们声称,如果在现行飞机的设计中采用这种
In the spring of 1983 at the Paris Air Show, the two largest producers of aluminum alloys for the aviation industry, Alcon Aluminum and Alcoa, announced the development of a new, revolutionary Material: Aluminum - Lithium alloy. The two companies independently developed this material. They believe that this new material is the most important development in the field of aluminum alloys since the invention of the Al-Zn series high-strength aluminum alloy (7075 aluminum alloy) in 1943. They also believe that the Al-Li alloy is the best answer for the aluminum industry to advanced carbon-fiber reinforced plastics threatening the aluminum industry’s status as a supplier of major materials for the aerospace industry. They claim that if this is used in the design of current aircraft
