[China Aluminum Network] Rio Tinto Alcan Group Alcan Global Aerospace, Transport & Industry business unit is committed to the development of high value-added: aerospace aluminum alloy plate, sheet, Extrusion materials, precision castings, high-performance advanced alloys (military and civilian aircraft and spacecraft), transportation equipment (automobiles, various special trucks, rail vehicles, ships, etc.) and general industry (semiconductor devices, solar energy devices, etc.) This kind of material. Among its sales revenue in 2009, the aerospace industry accounted for 42%, transportation equipment industry accounted for 37%, and general industry accounted for 21%. The business unit has eight factories under its jurisdiction, including two Issoire Aluminum Co., Ltd., which mainly produces high-quality aluminum alloy plates, and Ravenswood Aluminum Co., Ltd., West Virginia, USA. The company (Ravenswood), which has a large plate stretcher around the world. All of these companies have a very close relationship with the company's research and development center in Voreppe, France, with more than 240 scientists and technicians, and a 2500KN rig to evaluate the designed solution. . The AirwareTM alloy recently developed by the Wreep R&D Center has been patented. It represents a variety of alloys and is a generic name for a class of high performance aerospace aluminum alloys. Their overall performance is not only superior to common aerospace alloys but also to composite aerospace materials. The performance is even higher. The AIRWARE production line at Issur Alcoa produces a crucible process for each alloy strip, so each alloy can meet specific needs and can fully meet the requirements of aircraft designers. For example, AIRWARE2050-T84 alloy plate not only has lower density and higher strength, but also has better damage tolerance, and thus can objectively reduce the quality of the structure. The alloy is particularly suitable for the manufacture of large parts after the lower section, such as frames, beams, spars or ribs; the AIRWARE 2198-T851 alloy sheet has both high tolerance to damage and With high static mechanical properties, it is a good material for making fuselage and other internal structures. What is more worth mentioning is that AIRWARETM alloys are highly recyclable and have no impact on their performance after recycling and regeneration. This is of great significance for the development of recycling economy. The company paid full attention to this type of alloy at the beginning of development. a little. AIRWARETM alloy will be used in aircraft manufacturing. Alcan Global Aviation, Transportation and Industry has signed supply contracts with Bombardier and Airbus. The latter will use the 2050 alloy plate to manufacture the aircraft wing. (Internal wing) structures and forgings, Bombardier will use this alloy to manufacture the CSeries aircraft fuselage structure. The 2050 alloy is a new alloy registered in the United States in 2004. Its composition (% by mass) is 0.08Si, 0.10Fe, 3.2~3.9Cu, 0.20~0.50Mn, 0.20~0.5Mg, 0.05Cr, 0.05Ni, 0.25Zn, 0.10Ti, 0.20~0.7Ag, 0.05Ga, 0.7~1.3Li, 0.05V, 0.06~0.14Zr. Other magazines are individually 0.05, total 0.15, and the remainder is Al. This is a high-purity high cost containing Ag and Li. Alloy, but it's good value for money. 2198 alloy is also a new high-purity alloy containing Ag and Li registered in the United States in 2005. Its composition (% by mass) is 0.08 Si, 0.10 Fe, 2.9-3.5 Cu, 0.50 Mn, 0.25-0.8 Mg, 0.05 Cr, 0.35. Zn, 0.10 Ti, 0.10 to 0.50 Ag, 0.8 to 1.1 Li, 0.04 to 0.15 Zr, 0.05 for each other, 0.15 in total, and the remainder Al. At present, these two alloys cannot be manufactured in China. If it is necessary to use such alloy plates for manufacturing aircrafts and spacecrafts, it must be from Alcoa's Davenport Rolling Mill or French Canadian Alcan Company's Isso. Issoire rolling mill imports, and perhaps in the next seven or eight years China will be able to produce these alloys.
