C919 alloy wheels, passenger observation window precision forgings made a breakthrough


Ministry of Industry website 26, in order to improve safety and reduce costs, C919 alloy wheels and high-strength aluminum passenger window design uses the world's most advanced near-final molding precision forgings. Chinalco Southwest undertook C919 high strength and high toughness aluminum alloy wheels and high strength aluminum alloy passenger observation frame precision forging pieces of research and development work. Research team to overcome the lack of equipment, scientific organization, focused on capturing a series of precision die forging process problems. Wheelwise precision die forging pieces in trial production by the end of 2017, the sample was fully dissected, the performance of the United States Aviation Materials Standard AMS4413 requirements. The precision of the forging frame of the observation frame is also in accordance with the standard of China Commercial Aircraft Materials, and the dimensional accuracy basically meets the requirements.


The research team is optimizing the trial production process and plans to develop a qualified sample in 2018 and complete the preparation of the PCD and submit the user assessment and applied research.
