[Runbei Aviation Section: some of the localized aviation materials of Runhe New Materials have been approved by Comac process Materials of China] June 4, Runbei Aviation Co., Ltd. said in a recent investor survey that with the commercial operation of the C919, large domestic aircraft will also gradually shift to mass delivery, which is expected to increase the demand for aircraft materials in the aircraft manufacturing field, and bring development opportunities for the distribution of aircraft materials and domestic aviation materials. At present, part of the domestic aviation materials of Runhe New Materials, a wholly owned subsidiary of the company, has been approved by Comac process Materials of China, and the category will continue to expand in the future. Therefore, the commercial use of Comac C919 is also one of the opportunities for the company to localize its aviation materials business.
