The material industry in Chongqing is mainly composed of metallurgical industry and building material industry. In metallurgical industry, Chongqing is one of China's top ten iron and steel bases, China's largest ship steel base, China's largest aluminum processing base; including iron and steel industry and non-ferrous metal industry, with iron-making, steel-making, rolling, refractory materials, coke, metal products, functional materials, powder metallurgy, magnetic materials, etc. Electrolytic aluminium, electrolytic copper, electrolytic nickel, aluminium processing, copper processing, magnesium and aluminium alloys and other processes and technologies, perennial production of more than 2000 varieties of metallurgical products.
In building materials industry, a product system has been formed which integrates cement, glass fiber, sanitary ceramics, wall materials, chemical building materials and decoration materials. New materials industry, such as high-precision aluminium plate, foil, high-strength ship plate, temperature measuring material, new magnesium alloy, copper-based powder, high-performance glass fiber and products, has developed rapidly.
Key development directions and investment fields: advanced basic materials: advanced steel and high-strength steel for basic components, advanced light non-ferrous metal materials such as high-strength aluminum alloy, titanium alloy, magnesium alloy, copper alloy, advanced chemical materials such as high-end polyolefin, special rubber and engineering plastics, green building materials, special ceramics, etc. Advanced building materials such as special glass; key strategic materials: special alloys for high-end equipment such as high-temperature and corrosion-resistant alloys, high-strength light alloys, high-performance separation membrane materials such as reverse osmosis membranes, perfluorine ion exchange membranes, high-performance fibers and composites, high-performance rare earth functional materials, wide bandgap semiconductor materials and new materials Type I display materials, as well as new energy materials, biomedical materials; cutting-edge new materials: graphene, nanomaterials, metal and polymer additives manufacturing materials.
