Alcoa Fastening Systems (AFS) signed a strategic technology and commercial cooperation agreement with Commercial Aircraft of China, Ltd. (COMAC). This agreement deepens Alcoa’s existing partnership with COMAC, the main manufacturer of large passenger aircraft programs in China, and reinforces Alcoa’s presence in one of the world’s fastest-growing aerospace markets. AFS will provide COMAC with technical assistance in fastener and assembly tooling selection, joint design consideration, and quality system management. The technical assistance will include engineering, design, and training. In return, COMAC will purchase a significant percentage of its fasteners from AFS for the initial production of the C919 aircraft. Alcoa established a technology cooperation agreement with COMAC in 2009 examining advanced aluminum structural concepts, designs, and alloys for the C919 aircraft.
