COMAC is the main organization that is facilitating the building of large passenger aircraft in China. The company is mandated with the overall planning and development of trunk liner and regional jet programs, as well as the industrialization of civil aircraft. It is building the new C919 jet, which will use aluminum-lithium alloys and composites in its airframe structures.
COMAC also recently signed a long-term collaboration agreement with Bombardier. Initially, the companies will collaborate on four projects that recognize the similarities between the C919 and Bombardier's CSeries family of commercial airliners. One of the projects is developing standards and specifications for the use of aluminum-lithium in aircraft.
Several different companies and organizations jointly own COMAC, including the Aluminum Corporation of China, also known as China Aluminum Corp. (CHINALCO or CHINCO). CHINALCO has reportedly announced the third generation of its 540mm aluminum-lithium alloy for use in large aircraft.
The company has spent several years in R&D working on aluminum alloys for China's aerospace industry. The new alloy represents a breakthrough for China, and for its aerospace industry, since the production of aluminum-lithium has long been dominated by suppliers in other countries, the company's senior managers said.
