Advanced materials for the defense industry are a critical foundational technology in the global military sphere, indispensable to modern high‑end weapons and equipment, and a key area of focus in the development of military‑civilian integration.
Superalloys—key materials for aeroengines—are primarily used in aeroengines, gas turbines, single-crystal superalloy blades, and nuclear‑reactor equipment. In state-of-the-art international aeroengines, superalloys account for approximately 40% to 60% of the total weight. Research indicates that 50% to 70% of the improvement in an aeroengine’s thrust‑to‑weight ratio stems from advanced high‑temperature materials and their associated manufacturing technologies. The market for superalloys is projected to approach RMB 70 billion between 2015 and 2020.
Composite Materials—Sky Stone: Composites are among the most critical engineering materials driving advancements in the defense industry, primarily used in aircraft airframes and engine structural components. On today’s most advanced fighter jets, composites already account for 40% of the total material content, while on Airbus’s recently launched A350, this figure rises to as high as 52%. Over the next five years, demand in the military aviation market is expected to exceed 102,000 tons, with a market value surpassing RMB 20 billion.
Titanium Alloy—The Versatile Material: Titanium alloy is an ideal lightweight structural material, primarily used in aircraft structural components. In the F‑22 fighter, it accounts for 41% of the airframe’s structural weight; on the Boeing 787, its share reaches 15%; and in the V2500 engine of the A320, it comprises 31%. Over the next five years, China’s military aviation sector is expected to generate a titanium‑alloy market worth RMB 14.2 billion, while the civil aviation market is projected to reach RMB 26.55 billion over the next two decades.
Metamaterials—A High-Tech Revolution: Metamaterials are engineered materials that exhibit electromagnetic responses beyond the limits of naturally occurring substances. Currently, their primary defense‑related applications focus on metamaterial‑based stealth technologies, specialized antennas, and radar radomes. Over the next two decades, the market potential for metamaterials in the defense and aerospace sectors is substantial; the market for stealth coatings on military aircraft alone is projected to exceed USD 100 billion, while the market for naval vessel applications is expected to surpass USD 60 billion.
Ultra-high-strength steel: Developed to meet the stringent strength requirements of aircraft structures, it is extensively used in the manufacture of rocket engine pressure vessels and aircraft landing gear. By 2020, the annual market size for ultra-high-strength steel was projected to approach USD 1 billion.
