The slow development of domestic aerospace industry is mainly limited by the capacity of the assembly, materials technology and air traffic control policy, accompanied by a large aircraft assembly off the assembly line, and metal casting technology to enhance navigation and easing the industry is expected to usher in rapid growth. Reference to international experience and domestic air transport, military demand, China's civil aviation and shipping fleet is expected to add more than 2800 more than 50 aircraft, military four generations, three generations of fighters, UAVs demand size of about 2000. Navigation will also led to considerable demand.

　　Therefore, the aviation industry is expected to usher in rapid development, industrial chain with the huge demand for materials in the fields of fields of light alloys, high temperature alloys, high-end casting, 3D printing, carbon composite materials, and also requires high technology and Associate into the barriers.

　　Suppose that by 2030, China's civil aviation, military aircraft demand of approximately 2800, 2200, fleet size of about 5500, 6000, corresponds to the demand of about 98,000 tons of titanium alloy, casting and high-demand 3D printing component 250 000 civil aviation engine maintenance inspection needs about 1.2 million units, military aircraft engine demand exceeds 5,000.

　　With the domestic aviation materials gradually entered China Commercial Aircraft, supply system in the aircraft industry, independent from the material supply security and airline operating cost control perspective, the future of aviation materials to achieve domestic alternatives will become a trend, aerospace materials has been gradually advancing localization , import substitution and maintenance market is vast.

　　In 2016 and 2017 large aircraft first flew military aircraft and replacement of windows, has been part of the military aircraft entered the domestic / large aircraft certified supply chain performance of listed companies is expected to achieve reversal, open room for growth.
