International Trade Analysis of Aluminum-Magnesium Coated Plates
The aluminum-magnesium plated board market is characterized by "East Asia dominance and catch-up." As a major producer, China's output reached 12 million tons in 2024, accounting for 55% of the market, yet products like aluminum-magnesium plated boards for cars still rely on imports. Companies like Nippon Steel Corporation in Japan and POSCO in South Korea hold a 60% share in the automotive sheet market through technological monopolies. In response, enterprises such as Baosteel and Angang Steel are increasing their R&D investment, aiming to establish 5 dedicated automotive aluminum-magnesium plated board production lines by 2025. It is expected that by 2027, the import substitution rate will exceed 40%.
