Aerospace materials include two categories: metallic materials and composite materials, of which metallic materials mainly refer to structural steel, stainless steel, high-temperature alloys, powder metallurgy alloys, precision alloys, titanium alloys, magnesium alloys and aluminum alloys; composite materials mainly refer to metal-based composites Materials, ceramic matrix composites, carbon fiber composites.
According to estimates, the combined demand for various aerospace materials in the field of civil and military aviation in China alone will exceed 250,000 tons, of which the largest demand for aluminum alloys is as high as 200,000 tons per year; magnesium alloys, superalloys, titanium alloys, special The demand for section steel is about 1-2 million tons; the demand for carbon fiber and other composite materials is about 1,000 tons.
The global aviation metal materials market size can reach US $ 18.5 billion in 2025.
