美国铝业公司与空客签署了长达数年的高附加值钛和铝航空锻件的供货协议,总价值达1.1亿美元。美国铝业公司供应的钛部件及铝部件包括:空客最省油的单通道飞机A320neo上连接机翼和发动机的钛锻件;A330和A380上使用的大型铝锻件,如世界上最大的航空锻件——A380内后翼梁等。美国铝业公司还将采用7085合金锻制大型航空结构件,这些大型航空构件大多数为机翼结构件,其较高的比强度是提高飞机飞行性能的关键。美国铝业公司将使用其在俄亥俄州克里弗兰的5万吨压机进行生产。该压机采用了最先进的控制技术,能够生产出完全符合航空
Alcoa and Airbus have signed supply agreements for several years of high value-added titanium and aluminum aviation forgings with a total value of US$110 million. Alcoa supplies titanium components and aluminum components including: Airbus’s most fuel-efficient single-aisle aircraft A320neo on titanium forgings connecting the wing and engine; large aluminum forgings used on the A330 and A380, such as the world’s largest aerospace forgings - - A380 inside the rear spar etc. Alcoa will also use 7085 alloy to forge large-scale aerostructures. Most of these large-scale aerospace components are wing structures. Its high specific strength is the key to improving aircraft flight performance. Alcoa will use its 50,000-ton press in Cleveland, Ohio for production. The press adopts the most advanced control technology and can produce fully in line with aviation
