Alcoa Advanced Aerospace Alloys and Materials Used on China's First Home-Produced Regional Jet, ARJ21-700
NEW YORK--(BUSINESS WIRE)--Alcoa (NYSE:AA) announced today that several Alcoa-developed
high-performance alloys and products produced from Alcoa operations
worldwide are used on China’s first regional
jet, the ARJ21-700. The first ARJ21 rolled off the production line in
Shanghai last December and is expected to be ready for delivery to its
first customers in 2009. The ARJ21, developed by major aircraft
manufacturer China Aviation Industry Corporation I (AVIC I), marks the
first step in China’s ambitious plan for its
civil aircraft manufacturing industry.
Alcoa advanced materials on the ARJ21 include:
-
Advanced heat-treated sheet and plate alloys from Alcoa’s
Davenport (Iowa) plant are used on the airframe and throughout the
aircraft, where high-strength, toughness, crack resistance and
corrosion resistance are required.
-
Alcoa extrusions made from proprietary alloys and process technologies
were provided for the wing and fuselage stringers, floor beams and
seat tracks. The extrusions are sourced from Alcoa’s
Lafayette, (Indiana), Changwon (S. Korea) and Chandler, (Arizona)
plants.
-
Alcoa Fastening Systems’ specially
engineered aerospace fasteners including engine nuts, inserts and
studs are used on the two G.E. CF34-10A engines used to power the
aircraft. The G.E. engines are equipped with airfoil castings and
structural components from Alcoa’s Power and
Propulsion businesses in Whitehall, (Michigan), Wichita Falls,
(Texas), and Winsted and Branford, (Conn.).
“Advanced Alcoa alloys play an important part
in meeting performance goals of China’s new
regional jet. In addition, Alcoa worked closely with AVIC I on
determining material recommendations for various components of the
aircraft, as well as holistic factory floor manufacturing support on
such aspects as dimensional design and surface attributes,”
said Helmut Wieser, Alcoa Executive Vice President and Group President,
Global Rolled Products and Hard Alloy Extrusions and Asia.
The medium-range, 90-passenger aircraft is designed for decades of
service.
